If you don't want to change OS. Simply creating a non-admin account and installing ad-blockers will go a long way. Tell them most software on Internet have virus so install is blocked. Also enable remote desktop on all.
Edit: For some issues like airplane mode, see if you can remove them from quick access.
Strange that I had to scroll down this far for this answer. Creating a normal, non-admin user for them will greatly limit the damage they can do as they won't be able to make system-wide changes. I also disabled installing extensions in Edge.
I would never recommend something like iPad. I feel psychologically it makes you a passive consumer, while something like Mac/Win is more action oriented.
