For upgradability, bang-for-buck and plenty of ports buy a desktop. If you MUST have portability then you will need a laptop. I don't know but I suspect that any high end laptop suitable for high end video editing you will probably find that it has all the ports you will need.
One thing not suggested here yet but well worth checking out is whether the laptop has a docking station. Docking stations usually come with their own power supply which is often a higher rating than the laptop original one. And docking stations also have a few extra ports to expand on the laptops own. And it will either have its own plug to interface to the laptop allowing additional video ports for example.
I haven't checked this in possible laptops but docking stations these days are often interfaced through a USB-C port leaving the (almost certainly included) DP port on the laptop available for a primary monitor and secondary video ports through the docking station.
You will not find a laptop screen very suitable for long term video editing. They are small and almost never very good or easy to calibrate. Hence the need for a larger external screen. And the minute you do that you have lost portability so you may as well buy a desktop and have no downsides except portability.
I am not going to re-read all the posts but I don't think you have mentioned anywhere how you intend to use the PC so a lot of proposals are having to make assumptions which might be totally irrelevant to your intended use.

Docking station is interesting. I am a new Fuji GFX shooter. Quickly outclassed my laptop. Already, bought the wrong laptop and now determined to get the right one with external monitor. Almost there but this spec has been brutal!

Love it...one cable to connect/disconnect...SD card reader right in the front...everything else plugs into the back for a nice clean look (unlike my desk).

As it pertains to my objective with photography, I am trying to get to the final answer to assure I am leaning to an optimal setup. Discussions with Adobe (Lightroom/Photoshop), X-Rite Color calibration, and NVIDIA on the Pascal Series dGPU, I have concluded [AND I HOPE YOU WILL POINT OUT IF ANYWHERE I AM WRONG] I will be starting with a laptop but realize to have the full color calibration and control, I will have to get an external monitor (X-Rite software, by design, set the limitation and X-Rite explains why). With that said, to maximize my color depth and gamut, I am trying to assure my laptop to be purchased has the right monitors (internal and eventual external), the right connector on the GPU, the right DisplayPorts, and externally connecting the right wire. I have targeted using an NVIDIA Quadro P2000 (an Adobe for LR/PS tested dGPU). The Quadro Pascal (P) generation GPU and generations after, have DisplayPort 1.4 support.

I am starting with a 14 bit RAW file for photography. From NVIDIA I have read 8-10-12 bit per channel RGB can be carried but I want to be sure I thoroughly understand what else I need to optimize the bit carried internally and externally to the monitors that are calling for it.
QUESTIONS:
What should I be using for connections, DisplayPort, and wire to assure I am getting the optimal in color depth and gamut?
What should I be specifying in both monitors to assure I am getting the optimal in color depth and gamut?
Does DisplayPort 1.4A fit into the picture? What does the connector look like? How do I know if the laptop has it?
Does DisplayPort over USB-C (aka DisplayPort Alt Mode for USB Type-C Standard) fit into the picture? What does the connector look like? How do I know if the laptop has it?
Is there a reason to look for a laptop with BOTH DisplayPort 1.4A and USB-C DisplayPort Alt Mode?
Can the data be carried to an external monitor over a Wi-Fi network? to and external Printer?

There are a few more questions below:

DA-07089-001_v07 NVIDIA QUADRO AND NVS DISPLAY RESOLUTION SUPPORT https://www.pny.com/File%20Library/Support/PNY%20Products/User%20Guides%20and%20Tutorials/Quadro/Quadro-and-NVS-Display-Resolution-Support.pdf
In the referenced document, why is there no mention of HDR? Does the P2000 support HDR?
Pg 8 There is no single maximum resolution for a given connector type. The maximum resolution is defined by a couple of constraints which are different for each connector type
• The maximum number of pixels per second that can be carried across the link: It doesn’t matter to the graphics processing unit (GPU) if those pixels are allocated onto a single large desktop refreshing slowly or a small desktop refreshing quickly. The maximum desktop size allowed by the GPU is 16 k × 16 k pixels – the different operating systems may have different limitations.
• The maximum bandwidth available on the link: This is most important to DisplayPort connections.
Pg 9 Is Create Custom Resolution available when using a laptop with an iGPU on board? If not, how about when I get an external monitor, does that offer any workaround?
Pg 10 Is Change Resolution available when using a laptop with an iGPU on board? If not, how about when I get an external monitor, does that offer any workaround?
Pg 9 DISPLAY COLOR DEPTH
Along with the frame-rate and resolution, displays and connectors can also vary the bit depth of the color information for each pixel. Standards like DVI define that each pixel must be made of a Red, Green and Blue component 8 bits each or 24 bits per pixel.
Pg 10 HDMI and DisplayPort offer 8, 10 or 12-bit per component as well. The display device defines the bit depth that it wants to receive, and the GPU will honor it if it can. What could constrain the bit depth?
Pg 16 Common Supported Maximum Resolutions (at CVT Reduced Blank Timings)

NVIDIA Pascal GPUs
― 5120 × 2880 at 60 Hz 24 bpp
― 4096 × 2160 at 60 Hz 36 bpp
― 2560 × 1600 at 120 Hz 36 bpp
Do I need Multi Steaming if I just want to watch a movie or work on a 4k video?
Pg 18 Single Connector 4K (From the table and its note, there appears to be a lot of capability with Pascal)
Notes: Pascal generation and generations after, the GPUs have Display Port 1.4 support.

Thank you.

You can buy a Lenovo laptop with Nvidia built in and although the model I bought has been discontinued, it had the option of monitor calibration so that the laptop monitor could be calibrated. I also bought their docking station so that all my cables are connected to the back. I press one button to release the laptop from the docking station and just line it up and press down to reseat the laptop to the docking station. I do have an external monitor and it is connected with a DisplayPort cable.

Call Lenovo and they will tell you if they have a current model with monitor calibration built in and your Nvidia card options.

Just got off with HP. Lenovo is next.

Well I wasn't quite done with HP and haven't gotten to Lenovo yet.

Here are my few remaining questions that I am floating out to advisors. If a laptop won’t work, I may be into a desktop.

One of the laptop finalists is the HPZBookStudio x360 G5Mobile Workstation. I can turn off the iGPU on this machine and it comes with option of Adobe tested Quadro cards. However, RE its Dream Color monitor (an LG monitor…it used to be Samsung but had problems), 15.6"diagonal 4K IPS anti-glare LED-backlit, 600cd/m², 100%AdobeRGB(3840x2160), so far supervisor in ZBook Tech Support can’t tell me how many bit for this monitor or its LUT. I still intend to have an external high end monitor but what can I assume by the claim of 100% Adobe RGB for the bit?

Also, I am frustrated that this machine doesn’t have DisplayPort 1.4 or 1.4A. It has Leftside:1USB3.0;1USB3.0(charging) Rightside:1HDMI2.0;;1powerconnector;2USB3.1Type-C™Thunderbolt™3(DisplayPort™1.3). What am I missing by not having DP 1.4 or 1.4a?

Finally, Can you tell me where is the switch to turn off Automatic Display Control? This control may appear in the literature as ADC or DDC. It should be turned off permanently so there are no changes to the imagery when using LR/PS.

Thank you…

Cheers

The chances of you finding a laptop designed EACTLY as you want/need it is slim to none. I'm sure you realize by now that a desktop, which a much wider set of choices, would be much better in your case. Not to be stupid, but Apple makes those as well. I'm getting older listening to this discussion, which can easily be solved, if you lighten up just a bit. It's been a busy week for me. Since you started this discussion, I've performed PP on thousands of images, posted them or submitted them for publication and made a few nice prints. Best of luck.
