Having spent a whole hell of a lot of time lately on Gnome, configuring it and testing various configurations for rollout at the company I work for, all I can say is that it just works. There's a browser, and bizarrely, printers just work on Linux now in a way they just used to work on Windows, and it's now Windows, at least in an enterprise environment, where printing has become the technical equivalent of having your teeth filed down. Where work does need to be done is on accessibility, so we have one staff member who will stick with Windows 11 for now. Libreoffice's Calc is good enough for about 90% of the time, and Writer about 95%. We remain open to Windows machines for special use purposes, but most people after mucking around for a bit are able to navigate Gnome perfectly well, since once they're in the program they need to use, what's going on on the desktop is irrelevant.
On the enterprise back end, supporting global authentication has been around a long time, and if you only have admins who know how to navigate a GUI, then you have idiots. The *nix home folder is infinitely superior in every way to the hellscape that is roaming profiles, so already you're ahead of the game.
