Found a great site with info about privacy focused OSes written for non-technical readers. It lists basic things to know about several different mobile os options, and there are also pages that list what open source and privacy focused apps from F droid (the alternative to play store) are good to use.

There is also, wonderfully, a page that specifically lists user friendly and nice looking ones. This site is a goldmine. Had to post as I was looking for this exact thing yesterday and I know I am not the only person on lemmy looking for alternatives.
