So, I’m not new to this (omg it’s been 6+ years now wtf) but I don’t host a lot of stuff, and it’s been pretty easy to poke at; I’ve got:
plex
minecraft (bedrock and java)
freshrss
rustdesk
home assistant
vaultwarden
pihole
actual (budget software)
Running in docker containers, along with a few of the built-in plug-and-play services on my nas. Of that list, plex, minecraft, freshrss, rustdesk, and vaultwarden were very easy to setup in my situation. Rustdesk is a really good remote control program/service, vaultwarden is a fork of the bitwarden server, and plex was almost comically simple to get going as a media host.
