I have been self-hosting for a while now with Traefik. It works, but I'd like to give Nginx Proxy Manager a try, it seems easier to manage stuff not in docker.
Edit: btw I'm going to try this out on my RPI, not my hetzner vps, so no risk of breaking anything
Caddy. I started with npm but I realized it was hiding enough stuff that I wasn't learning anything about managing networking. Caddy is super easy and has lot of sane defaults.
