Don’t use an immutable distro like endless or silverblue. It’s a whole new paradigm to learn (in addition to learning Linux basics). You should get your feet wet with something more user-friendly first.
My big recommendation is Ubuntu. Normal ubuntu. Not one of the flavors or derivatives. It’s got everything you need, plus very easy to troubleshoot if something goes wrong. Try to avoid using the command line when following guides online, there is nothing on Ubuntu you actually need it for and the graphical tools are very good.
Don’t listen to the complaining about snaps. You won’t notice them, they won’t affect you negatively, they are designed to just set and forget. The complaints come from a highly particular and technical subset of the Linux community.
If you really don’t like the look of Ubuntu, then I’d second all the recommendations for Mint. Those two distros have the most number of non-technical users in their communities because they are both very user-friendly and well-tested. I’d recommend against trying anything else until you’ve gotten comfortable with Ubuntu or Mint.
