Look, I’m a Slacker. It’s not the Slack way.

That depends on what the beginner’s goal is. Arch could very well be a nice beginner distro, as could Gentoo or Slackware or any other “hard” distro if you’re determined to learn. My baptism of fire was on Slackware in the 90s (which I’m still on), long before “beginner distros”. Trying and failing was a big part of the fun. If you’re determined to learn, I don’t see any issue with starting with a distro that doesn’t hold your hand.
