Exactly - 27" 1080p is too large, 27" 1440p is nice for UI size for me, and then it's about extra pixels for sharpness & clarity.
Unfortunately the OSes I want to use don't do fractional scaling well - macOS or Linux, but Linux can work here, it's getting better. Windows does fractional scaling well in theory, but I find it works poorly in practice as app support for it is really patchy.
