Beautiful setup!

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.
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.
Just found it and tried on my home server, it works:
version: '3.3'
services:
yarr:
container_name: yarr
image: maskalicz/yarr:latest
ports:
- 7070:7070
volumes:
- ./yarr-data:/data:rw
Anyway, it just have one view mode with 3 panels and it's not customizable. At the moment, the most featured and exstesible RSS Feed service seems to be FreshRSS as suggested in the thread by @specseaweed@lemmy.world.
The soundtrack remake by Katod is great: https://youtu.be/eTVzkftwYgM?si=U-wyxtNqEyhaFLzE
