It can be a great experience. I used to work in a program for teaching informatics to people who didn’t have access to technology, and we used linux. The results were great. Most people who came from a phone-only background would feel more comfortable with gnome as a gui, so I’d recommend a gnome-based distro for you, like ubuntu, pop os or fedora. Don’t think too much about the distr, just pick one and give it a try. And don’t forget to post your experience here later.
