Welcome aboard! There is no need to be a programmer to work on Linux. I’m no programmer either and have been enjoying Linux for many years.
About the distro, it’s a conversation ad old as the first fork lol. It depends in part what you want to do with it. I’ve used many in 20+ years. I’ve settled eith endeavourOS for my desktop (after a few years of Linux Mint) and debian on the servers. I play and work on it without any problems (although I have a radeon rx580 card).
I’ve never used popOS, but all major distros have a fairly simple install process, especially if you use the whole hd and don’t need fancy config. Or you can start relatively hard and use gentoo. It will take a while (and thanks the fact that stage1 is not the default anymore) but you’ll learn a lot of how linux works.
