For a total newbie, Linux Mint or PopOS are probably the best options. But EndeavourOS is getting there. There shouldn’t be any issues during the installation if one sticks to the defaults. Only thing is, it doesn’t come with a graphical package manager out of the box. But once that is installed (I think anyone will be happy to write a single terminal command, at least), I don’t see why it’s any harder to use than any other distro.
