I personally like Syncthing for petty much everything else. For general file syncing of course. But also with Joplin pointed to a synced directory for notes. With keepass as a password vault. With synced config directories for some apps across devices like newsboat for RSS, and neomutt for email. I also used to use it with rtorrent via a watch directory, though I currently am using a seedbox for that purpose.
VPN (openvpn/wireguard) is a good idea if you want to access your services outside your local network, without exposing them all globally.
Jellyfin/Plex like many have mentioned.

I believe Syncthing has been discontinued unless someone else took up the project.
