If you're not afraid of Docker you can even spin up your own instance of Invidious. You won't get much in the way of recommendations, but you won't have to worry about the site going down.
That's a way taller order than you might think. Docker has loads of kernel level integration that FreeBSD isn't interested in supporting, also there are separate techs for similar purposes, like jails.
The problem with podman is that we use stuff like Docker-compose and tilt at work, that require the docker daemon socket. I do try to use podman when possible, though. But yeah, I avoid Red Hat these days, that company is doomed.
I use kubernetes+containerd for my servers, which is neither Docker nor Podman.
