The soundtrack remake by Katod is great: https://youtu.be/eTVzkftwYgM?si=U-wyxtNqEyhaFLzE

If I well understood you, what you want is Debian with a great intaller. Don’t search anymore, there is the great Spiral Linux! Enjoy it.

Lutris is not a valid alternative for Linux?

This is an intuitive PDF page editor for linux: Pdfmixtool

You could try Linux Mint Debian Edition (LMDE) it has timeshift installed in the live iso, useful to restore a system when it’s unbootable. Anyway it doesn’t come with KDE but Cinnamon or XFCE.

For me Debian or LMDE is good for a home server due to not continuous package update, just major security an important ones.

For a Deskop or laptop in my opinion Fedora KDE or Gnome is the best experience.
