The table linked here seems like a reasonable starting point. I can't remember where I found this, so it might be up-thread 😅
Anyway, even ignoring Mac compatibility, 4K 27" falls in the badlands that are more likely to need fractional scaling/less likely applications are tested against.
27" 5K should work for anything tested on retina displays or with integer (2x) scaling.
I'd be concerned that 4k @27" will require UI scaling to avoid everything being too small, and therefore potentially ending up in the same situation with Slack and other apps.
