You don't need to be tech savvy to use Linux there are more than enough distros where you need as much knowledge as you need to use windows I wouldn't call everybody how owns a steam deck a tech savvy person. The only user friendly advantage is that Windows comes for some reason preinstalled on almost every device. If this weren't the case and the average consumers had a choice the picture would be very different.

I know I am very late to this party, but I think alpine Linux is the OS you are searching, I only used it in docker but it is indeed very small. (Only half a gig or something) also if something has a USB Port but not much disk space maybe use a live usb-stick distro like tails (also quite practical when you don't want to be spied on). Hope that helps with a future project.
