If you can figure out Docker then just go with that and avoid Supervised.
I have yet to be limited by anything that I absolutely needed Supervised to run that I couldn’t get to run in a stand-alone Docker container.

Yes, I have 4 instances of HA installed (2 always running including a Supervised version) that I use for testing.
Some of those other containers aren’t running as well but I can start them as needed.
And that’s the beauty of Docker. You can install some app, test it, turn it off or remove the container and the system never even knows the difference.
I just did that yesterday in testing PiHole vs. Adguard Home (on a different system). I installed both but since they use the same ports I couldn’t have both running simultaneously. So I could easily switch back and forth between them as easily as stopping one container and starting the other.
