For sure choose some Debian-based distro. As a beginner maybe stay away from Arch or Fedora derivatives - most tutorials are for Debian-based distros and it will be easier that way. Pick something like Ubuntu, Mint, Zorin or sth like that. Don’t be owerwhelmed. The distro doesn’t really matter as long it’s not Arch. Learn that the look of the desktop is independent of the distro you choose. The look is called “desktop environment”. Look it up. You can install any desktop environment on any distro so you don’t have to pick distro based on looks. Good luck and have fun.
