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...
