I think a possibility is a series of open source anvil or nixos scripts that you can run on most hardware with minimal changes, in an extendable architecture of some kind to add or remove functionality and they perhaps get maintained by the community or some structure of the kind of Linux distributions.
This could enable people with minimal skills set up and maintain a reasonably useful but secure environment just by changing a few variables.
I don’t mind Ubuntu server, though you’re right you need to clean it up a bit by uninstalling snap and killing the login ad of managed k8s, the LTS versions have been quite consistently easy to deal with and stable, but then again so has Debian.
