I just start pointing this is my opinion and maybe someone can point one
that maybe better fits common sense, but I have a 4k basic 27" IPS monitor, and honestly, 4k, 2k for me are the same while painting. But for sure for letters and precise information on vectorized info it will make a lot of difference, I believe photo editing is the middle term, I've seen 4k photos that 1080p monitors lose details like full of star skys, etc.
So you must see what is more relevant in your work...
I have no use for wide gamut monitors, most of my work is not intended for printing and even so I would need to figure if someone here in my city has a printer that can take relevant advantage of this, I mean, honestly I have zero experience with wide gamut, I'm not even sure it will result in any advantage on color proofing for "common place" printers or image edition.
...and at same time, what is honestly needed.
So I personally would go for a precise sRGB representation 4k monitor.
