Personally I use Linkwarden for keeping snapshots of websites as well as a bookmark manager and Memos for a simple note-taking app. Both can be installed on mobile as PWAs, so it makes it easier to access on-the-go.
I'm using Nginx Proxy Manager, which I highly recommend for new users due to how simple it is get set up and running! NPM renews SSL certs automatically before they expire as well (afaik). You just gotta make sure that your different Docker containers' ports don't collide with each other.
I hope you have fun with Linkwarden!
If you don't mind me asking, why did NPM push you to quitting homelabbing?
