Do your co-workers not have issues with HiDPI support on Linux? I've heard it's not the best experience and can require quite some fiddling to get working correctly.
HiDPI on Linux is pretty much non existent. I am telling from experience. I have booth a decent 4K external monitor and a HiDPI IPS internal display. The only setup which is ok in the sense of least horrible is Gnome mutter Wayland with experimental per monitor fractional scaling enabled. And this one is only ok if you can restrict yourself to the few ported pure GTK3 Gnome apps. Which means not that much. No Firefox…
That sounds like a draconian restriction if you are coming from Windows 10, but OP is switching from macOS. Macs have traditionally used either 100% or 200% as well (except for the latest-gen MBP).
