Holy shit people, I had heard of #yunohost and I knew it had some good apps, but I didn't realize just how many things you can point and click install, so I think that solves my problem of deciding what to use for my expanded #selfhosting schemes... Peertube, Immich, Cryptpad, Forgejo, Ghost, jitsi-meet, and such here I come...
I think the only question is whether I should maybe attach a whole USB drive just for that VM.
