Lots of simple scripts to set up new stuff, remove annoyances, easy updates...
I have switched from bare metal running on Rpi4 to proxmox and I've been super, super happy with it. Things like snapshots and backups make everything a breeze, and it's really solid.
I have tried Docker and some alternatives, but I think I'm too stupid to understand them. Proxmox is really straightforward and relatively noob friendly. It's also very reliable. It just works every time.
