This should keep you busy for some time. ;- ) =
Everything is complicated, till it isn’t any more.
I would suggest looking into TiniMiniMicro project.
And considering ProxMox as a platform. It will save you your nerves so much. Spin up a VM/LXC in a few seconds, play with it, delete it. Make a snapshot before update, if something fails - revert back. I’ve tried so many new projects because of how easy it is to do it.
