I run proxmox bare metal (debian-based hypervisor) and virtualize debian which has all my docker containers.
with virtualization you can take a snapshot and backup everything that way. super simple to roll back if you mess something up. the added bonus is you could probably take a snapshot of your VPS and migrate it to a local vm.
Ubuntu is something I played with about a decade ago and I never felt like I was “missing” something for debian, especially on servers.
you could definitely run proxmox in a VPS but I was thinking more of debian in the cloud. Then exporting that computer from wherever you host it as a ova file then importing it into your local server: https://pve.proxmox.com/wiki/Migrate_to_Proxmox_VE#Automatic_Import_of_Full_VM
and on the ram issue, I’m running on over 10 year old workstation hardware ddr3. it doesn’t take much to run.
NAS with zfs storage does typically want a lot of ram (e.g. truenas) but still for a small home environment it works fine with a lot less than 64gb.
