I've been trying to not use Steam on linux for a while now unless necessary (I have too many games there). GoG + Heroic keeps me pretty sane. Otherwise it's Lutris for starting them (which I'll agree is VERY clunky but you can get things done). I think we're actually getting over the hill of "Linux gaming means Steam" that we've been on since the SteamDeck launched.
While it’s working fine for now, what do I do if I’m offline and Steam decides this is one of those days offline mode doesn’t work? What if I get banned from Steam?
This is a pretty valid-ish concern I would say. It's one of the reasons I'm using GoG mainly now (which yes, still buying licences so similar concerns just maybe not as great or maybe I'm kidding myself)
