Oops. Sorry about that. Both images are posted - the original and a second with a little brightening to see it.
How much cropping and sharpening did you do in post? A lot of either will make the noise worse. Your just magnifying. Personally I don't think it's bad at all. If you got it right in the camera that's probably the best the camera can do.

I think that you are being much too demanding of the 750. Image looks fine to me.

The shot looks under exposed. What did the light meter say that's on the bottom of the viewfinder?

Your shutter speed is slow enough to cause blur and your aperture provides little depth of field.
Go up to 10,000 ISO or so with a faster shutter and smaller lens opening and see what happens. I have shot at 24,000 ISO with my Nikon D7200 and got acceptable noise. I also shoot on program and get great exposures.

Thanks for all the great suggestions - sounds like the consensus is I'm over thinking it a bit. I thought leaving the aperture wide open would bring in more light, but will follow one of the suggestions here to bump the ISO up even higher, close the aperture down just a bit, and shoot with a faster shutter to see what happens. I was using spot metering and someone suggested using center weighted, so I will try that also. Unfortunately I'm no longer in Asheville but can certainly practice around my own home at night to try to get this right.

This is what I can do in Lightroom for your image. Topaz would do better.
Beautiful! I do have Topaz but having been using mostly LR and Luminar 2019. I may go back and give Topaz another try....

If you don't nail the exposure, noise will be more present than if you do. You underexposed and then pulled the exposure up in post. This will be noisier than properly exposing the image. But, in the end, I don't find the level of noise in your shot objectionable.
The original doesn't show that much noise. I agree that the post processing to brighten the exposure is responsible for adding noise to the processed shot.

Opening the aperture technically brings in more light but if you are shooting in an automatic mode the camera will adjust the shutter speed. You need a smaller aperture to get more depth of field and more in focus.
Use center weighted or matrix metering if you have it. But if you are shooting rooms why not just use a tripod?

These were taken at the Biltmore Mansion and they do not allow tripods or flash. So that wasn't an option....

If you have to increase the exposure by two stops, then your effective ISO is two stops higher (i.e. 2200 becomes 8800!). But it's worse, because your read noise has a greater impact at low Ev levels. Crank the ISO to get an appropriate exposure; and use stabilization to reduce the shutter speed.

As many have said, underexposing and then boosting in post tends to show noise in the shadows. Two things I do when there isn't much light. One: I use the power of digital and, at really slow shutter speeds with static subjects, I shoot multiple shots of the same thing. I am not talking about burst mode, but, four, five or six identical seperate shots. On the computer one of those is almost always way sharper than the rest. One shot or six shots, the cost is the same. Two: Sometimes if I boost the shadows and they start to look bad, I decide if I really need the detail there. If I don't I will let them stay dark, hiding the noise, and then do something to draw the viewers eye to the main subject. I would usually rather have dark shadows than noisy shadows.

I regularly use Topaz Denoise as a plug-in in photoshop cc2018 with originals from my D500 Nikon shooting only in RAW mode.. I find most of the time I can find a nice balance between noise and sharpness on ISO's up to 6400, although it's really easier in most situations to go to ISO3200, which is my standard for a lens optic that is wide open at F6.3. I think comparisons have been made between the crop sensor D500, and the FF D750 in the noise category, and being a "newer design", the D500 seems to have less noise than the Full Frame D750 from what I've read.

I don't see any objectionable noise in the raw or processed image either. One thing that I would comment on is that you need to use at least f/5.6 for a decent DOF or focus at 2.8 on what you consider the more important subject, not just the center of the room. I think the images need more detail. The shutter speed was too slow and I think that is one thing that contributed to your lack of sharpness. Increasing f/stop and shutter speed though are going to give you more noise, but it would not be objectionable, given that the sharpness is more important than noise is.
I have a D750 and I love the dynamic range in this camera. You were able to hold both highlights in the table lamps and the shadows--both in the same image--so I congratulate you on your choice of cameras. Not many cameras can do that!
After you make the aperture and shutter speed adjustments, you can then process in Topaz AI Clear and you will have some great images. I know it.......
