definitely don't expose any management interfaces to the open internet.
personally, i manage my homelab through ssh via the commandline, and key-based ssh auth is secure enough for my threat model (i am considering switching the entrypoint machine to a BSD though, to avoid the kind of bugs distros sometimes introduce).
but a webserver and a few containerized services seem pretty low risk to me, so i do have a few of them exposed via reverse proxy. The more sensitive one behind Authelia via the forward-auth pattern, which i feel like is a really good fit for homelabs.
