NixOS makes this rather easy too. There exist modules for synapse, livekit, etc (MAS module is still a Pull Request, though) and the setup is quite doable: https://wiki.nixos.org/wiki/Matrix

However, you still need to know what you are doing (the manual helps) and connect the pieces (in theory there could be a nixpkgs module that does this for you but apparently nobody did bother). Once its done you can lean back.

I've been running my homeserver happily for > 5 years and it was fairly straightforward.

Yeah, but then you have to run NixOS, which besides the sheer difficulty of being Linux, for the average user, stacks Nix on top, which comes with its own learning curve.

Also, based on your description, you're a techie. I highly doubt the average city hall clerk will set up their on Matrix server.
