For pseudo-casual I’d suggest Pop!OS. It’s what I have running on my wife’s machine which is an AMD CPU and Nvidia GPU. She claims not to be a techy, but I think it’s more that she doesn’t want to be bothered with tinkering.

I haven’t paid close attention but I think she started a cult or something.

Yeah, it seemed like a disturbed old lady hurling abuse and calling the cops on everyone in the neighborhood, especially the kids who were playing in an empty yard, that she did not own, next door to the woman’s apartment. The kids had permission from the owner of the land and he even played sports with them there.

There’s video of her trying to get the cops to trespass a man out of the parking lot while they interviewed him about a prior complaint she made against the kids playing.

It’s a goddamn synapsid you little shit!

Even if the game is a repack, you can add the installer EXE to Steam and it’ll run with Proton Experimental or GE, choose the install location, then add the resulting, unpacked EXE to Steam and it’ll run just fine.
