Issue tracker for Linux version of Steam
It's been a few years since I used Mint, but I enjoyed it. Most of the Debian-based distros are very similar, actually. All are decent for beginners. If not Mint, Pop is another good option.
Also Zorin
I installed Zorin on my wife's (=no prior Linux experience) laptop something like 2 years ago. Considering the fact that she still uses it almost daily, I'd say you're right.
Personally, I dislike some of the custom stuff it has over the more standard desktop environments, but I do think it's great for usability in that it feels Windows-adjacent.
