I started with Red Hat 6 (not RHEL) as a kid, because it was what was included with the book on Linux that I was gifted. Some time around 2000, I was given some retired beige powermac G3 desktops, and I switched to Debian for its PowerPC port. I've been with Debian ever since.

So maybe pick something with the realization that they may stick with it for decades. :)

I also kept Windows on dual boot so I could play UT99 with friends. The social aspect is also important. My son is comfortable using our Debian machines, but also has Windows on his primary desktop so he can play Roblox and Minecraft Bedrock with school friends. I wouldn't want him to lose that.
