You'll get plenty of answers with different suggestions, so I'll suggest checking in that community for plenty of previous answers. I would say to stick with "main" known distribution and to ditch specialized ones. https://linux-myths.pages.dev/Single-Maintainer https://linux-myths.pages.dev/Distros
I'm on Nobara but despite the fantastic work of GloriousEggRoll, it did had it's lot of breakage which made me want to switch to the suggested uBlue Fedora atomic builds, per those criterias.
To be fair, I'm in the same situation. Fedora, Libsteam_api.so and more dependencies and all. Do want to share it out, even if I didn't work for me. No idea if it is a case of “Source only” or if the devs don't really know what they are doing and forgot to remove non-free dependencies like the Steam Integration.
