I went with a BenQ 32†monitor at 2K resolution (2560 x 1440) since 4K was too much for my system. The PPI (pixels per inch) is 91.79 which is the exact same PPI for a 24†monitor at 1080p (1920 x 1080). Flight Sim looks great on this 32†monitor and it doesn’t stress my video card. I enjoy the larger screen size especially in the virtual cockpit. What’s also nice is if you pair it with a 24†1080p monitor there is no change in scaling of windows when you drag them from one monitor to the other since they are both at 91.79 PPI.
I first tried a 27†1080p monitor but was not happy with it because the images were not as sharp as my 24†1080p because the PPI on a 27†at 1080p drops to 81.59 so gauges and things are not as sharp so I then went with the 32†2K.
So whatever you decide for size and resolution keep in mind that the bigger the screen size you go you will lose sharpness in the image unless the resolution increases to increase the pixels per inch PPI. The image on a 27†1080p looks worse than the image on a 24†1080p because the resolution doesn’t change but the PPI drops on the larger screen size.
If your video card can handle 4K then I would do that. You could do 27†but if I was doing it I would buy a 32†or larger. A 32†4K monitor has 137.68 PPI so it’s very sharp and looks great. Once you get higher than 32†though I think you have to buy a TV and that was too much for me on a desk.
Here is a good PPI (pixel per inch) calculator to use as you shop around:

Keep in mind if you are currently at 24†at 1080p you have 91.79 PPI so use that as your factor when deciding on a new monitor. You will not be happy with the image sharpness of a new monitor if you buy something that has less PPI than what you currently use. At least I wasn’t.

Good luck and let us know what you end up buying!
