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’m also the signal guy amongst my friends and family. There are dozens of us!
