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.
