I was fiddling around with different monitor sizes and resolutions and found that 27inch and 4k works very well for me (at 2x native resolution setting). Everybody said that 1440p or 5k was best for a 27inch monitor, but for me personally, fonts in menus and apps etc were just too small, whereas they look perfectly sized at "looks like 1920x1080". As a positive "side effect", fonts look crips and performance is superb (though I tried out a 32inch 4k display at "looks like 2560x1440" and performance as well as font rendering were absolutely fine).

I would say that's a personal preference thing, however. 27 4k works for me, because my eyesight is rather bad and the slightly bigger scaling with its magnifying effect has a positive effect on my routines (I also set my 13inch MacBook Pro on "looks like 1280x800", others don't), given that my glasses make everything look smaller in the first place.

So you should definitely try out which font sizes suit you best in person, just trusting other's visual experience might not be the best idea - especially since you were talking about "old eyes" in your case as well.
Also keep in mind Mac has zoom-on-demand options in Preferences. I’ve set it up to zoom in when I double tap with three fingers.
