If you mean for picking which distro you like, assuming you don’t want something unique like qubes or nixos the only thing that really matters is DE and package manager, everything else you can install/uninstall as you see fit (if you really want to you can change the DE yourself too)
Every Debian based distro is the same operating system underneath with different stuff installed, every redhat based system is the same story
That said certain distros come with a lot more pre installed that you probably want (for example the zip command)
