You can go with mint. It's a solid choice. I prefer opensuse tumbleweed since I find it easier to work with. It also has a great selection of desktop enviroments witch is the thing you interact with and what you use to manage your open programs. If you want something like modern windows you can go with KDE or cinnamon and if you want something more minimal and windoes XP like you can use xfce.
Calyxos user here. I like it so far. Half a year into it. I can live with microg instead of gms. And it also works on moto g32, 42 and 52 so you don't need Google hardware.
Su Linux is most likely the answer to lering younger people to use computers fedora is especially good becouse it has a nice package manager (dnf) that is easy to understand
