Return to Castle Wolfenstein with RealRTCW mod.
I know, and it's heartbreaking. To be honest I pirate sometimes their binaries for conservation. If the dev deserves it, I buy it later. I think it rewards them more money than Steam at least.
There are new-ish titles ! But i agree that their main selling point is long conservation repacking. No DRM packs that can linger on drives or clouds forever and it should still work as long as the OS allows it.
Your 2nd paragraph sounds just like GOG ! I tend whenever possible to get my games from GOG than Steam.

I'm not sure it will 100% suit your use case but definitely a solid choice.
Garuda Linux ? (Gaming focused Arch derivative)
