I see some CPU and memory usage on my setup… but I don’t even see any IO!
Literally, the IO chart for “week (maximum)” on Proxmox for my Nextcloud LXC container is 0, except for two bursts, of 3 hours of less each. (Maybe package updates?)
The PostgreSQL LXC container has some more activity (but not much), but that’s backing Nextcloud and four other applications (one being Miniflux, which has much more data churn).
Nowadays, with Flatpaks, so many software providing binaries, etc. this does not matter so much. If you want, you can even use something like Distrobox to have containers for tools using whatever bleeding edge distro you want, but still have a solid stable underpinning.
Debian also has more stuff than you would expect in backports. The main sticking point is yes, you’ll be stuck in Debian 12’s KDE until 13 comes out. But that might be sufficient for you?
(You could also use Debian Testing, which is basically a rolling release. But I’d consider stable first.)
