If you are new I suggest bazzite, and get lutris to install windows apps outside of steam. It takes care of most of the stuff and to install software, on bazzite you use "sudo rpm-ostree install " and then reboot because bazzite uses an ostree system, or just get it in a flatpak if available. Between bazzite and knowing how to install packages outside of the flatpak repository, that should cover most of your bases for a few years and you can learn other stuff when you have the inclination. ChatGPT is really knowledgeable about Linux since it's open source. It's often much faster than digging through forums just be specific when you speak to it.
Also if you get your setup in a decent shape, you can shrink the partition and image it with dd with a single command, and then compress it to have a full system backup, which is basically your own image. Then you just write it back with a program like etcher later if you screw up your system and then just reexpand the partition to the full drive. If you get bazzite though you won't have much need to use the terminal or install anything outside flathub which will keep you from breaking the system. Also update the system occasionally, to get security fixes once a week or two is probably fine if you don't have open ports to run a server and aren't running random software.
