I had a 55" TV as my main display in 2022. Had it about a foot away from my face. It takes a few days, but your brain and body get used to the size.
I just bought a 39" ultrawide and for the first few days I thought "oh dear, I have to keep turning to see the whole thing," but I've not even thought about it for a couple of weeks now, so I guess I'm acclimated.
I have been using a 32" monitor for the last 10 years. I have found that I am using mostly the center of the monitor. The peripheral edges remain unused.
If I sit far from the monitor, then the FOV could be reduced, but then I have to increase the font size defeating the very purpose of maximizing screen real estate.
This is pretty much what I concluded as well after using my 43" 4K LG monitor for about 3 years. Lately I've been trying out my wife's 27" Apple Studio Display. It's smaller but the PPI is amazing...

YMMV.
