I’m scared that the world is going to run out of popcorn because the Chinese are going to eat all of it.

Out of recommendations given here I’d ignore Arch/Manjaro, for a server you want something that you can set up and forget about and not explode when you try to update the packages after not doing so for 3 months.
Kubernetes and the likes are a bit of an overkill unless you’re planning to expand to having multiple machines or want a learning experience.
I’d recommend docker compose or podman, you generally don’t want bare bones docker as running your containers via docker run sucks ass.
