I have the Nikon D810 that has the CF/SD card set-up. I use the cf for the primary photos card with the sd set for overflow & movies. The sd records movies just fine at 1080/ 60fps fps me. When I shoot wildlife, the sd is much slower than the cf. I put my cf in & all the time to upload photos to the computer through a card reader without a problem but am sure the warnings are for good reason. You probably could leave your cf in & transfer via usb cable without removing the card unless you fill it up on a shoot & need to put in an empty card for more shooting. Enjoy your new camera.

You didn't specify the camera you are using, or the type of photography you are doing. If you go for the pricey new SONY A1 or Nikon Z9, they use CF Express cards. SONY uses type A, Nikon (I think) uses type B. The SONY also allows use of SD cards.
I shifted to a SONY A1 about 6 months ago. I initially put in one CF and one SD card. After two days, I bought a second CF Express card. I initially found little difference in performance between SD UHS-II cards and the SONY CF Express. But as I became more familiar with the A1, shooting mostly Birds In Flight (BIF) at high frame rates, the CF Express Cards proved their worth. When shooting at 30 Frames Per Second for more than 3 seconds, the concern is filling the buffer to the point that the camera may no longer keep up with your rate of shooting when using the SD card. That is very unlikely to happen when using the CF Express card.
If you are shooting landscapes, streetscenes, macros, etc., then the very expensive CF cards have little benefit. Save your money and go with a good quality SD UHS-II card. If shooting BIF or race cars, sports with fast action, especially long runs of several seconds, you will find that the CF Express cards are well worth the cost. This is also beneficial when shooting high speed video at 240 FPS, 8K and 4.2.2. It won't make any difference with standard 24p/30p video.
As with so many things in life, the answer always starts with "Well, it depends...."

I have an Olympus E-30 that has CF and xD Picture Card slots. I don't have any xD cards but I do use a CF Adapter in which I insert a SD card. So I don't need to invest in more CF cards and I can insert the SD card in the computer to xfer the contents. Problem solved!

Do you have to remove the adapter to take out the SD card?

My new-to-me Nikon D500 uses both QXD cards and SD cards. CFExpress cards are a drop-in replacement for QXD if you update the camera firmware. CFExpress are about $1 per GB, which is much cheaper than QXD, but still more than SD.
Considering that I have plenty of SD cards in 32GB and 64GB capacities, I'll stick with the SD cards for now.
I am also a hobbyist, not a pro-level photographer with a lot on the line.

Yes.

Then you can bend the pins removing and inserting the adapter just like a CF card if I’m understanding you correctly.

I could, but I haven't yet. Nor on my old E-3 or my Lumix L1, not that I ever use those two these days.

What is slow, seconds or minutes ? I think the longest time for a transfer has been less than 5mins I don't remember how many RAW files there were.
I have been using CF cards for many years ( since the iSTD Pentax hit the market), and have never had a problem with pins getting bent, the only way I can see this happening is too really be careless and FORCE a card into the camera, I mean geez they have guide slots on both sides of the card and slide in easily.
As far as transfer speed I don't a Big difference, My D7100's used sd 2 cards everything else I own and have owned used CF and/or a combo of CF/SD, the only reason I prefer CF is I can handle them easier,( big fingers).I also remove the card and use a reader to transfer images to the computer, I have had to replace a couple of readers, but not a big deal. I'm still using the same cards that I started with in My D800 and D810, I can't remember how many years that I have had them. I do prefer the 4-8gb cards but I have had to go 32 gb since because the smaller cap. cards became obsolete, I hate having all my "eggs" in one basket!!

I have seen bent pins on automotive ECM's and can see how it happens, the connectors are a sloppy fit ( compared to the cameras) you start the into the ECM until the retaining screw makes contact then tighten the screw until the plug is seated, I have seen two pins bent, since the ECM was damaged and unusable I straightened one pin using a special tool made for this purpose, the second pin was bent almost flat and broke off, This was 104 pin processor, and not all pins were used so I installed it and it worked! Granted the pins in an ECM are much larger than the ones in the camera, But you pushed then in using a nut driver.
