My thought was XFCE feels a lot like XP/7 era Windows, and so would be familiar. But I can see Budgie being attractive for someone where it’s just like “here’s the button for your email, here’s how you get on the internet” and they don’t need to touch anything else.

If they are used to Windows, go with KDE.

I’d say Cinnamon or XFCE. Plenty customizable enough for this use case and very straightforward.
