Sure the daunting setup process would fall into the "a hobby" category but once it runs it tends to just keep running as long as you update it from time to time.
Using it now for ~5 Years and in that time I had two times problems one was that the new kernel version didn't work with my laptop and another which was fully my fault by doing some "special" boot setup with some custom self written package and not maintaining it. Oh and the only reasons they where problems was because I never setup recovery boot or boot prev. kernel version.
Besides that I remember having more work with maintaining Ubuntu when I used it ~8 years ago.
Also disclaimer I had some more work like setting up edurom with network manager without using any proper UI for it (nmtui...). It's doable but not properly documented. But non of this is a problem if you "just" use Gnome or KDE or at last part of the tooling from Gnome/KDE.
EDIT: But Fedora is probably what you are looking for. Widely used, well maintained and normally up to date.
