For use on a VPS with an external IP, I've had success with this https://github.com/Nyr/openvpn-install

For use to connect to home network drives, I've used ZeroTier https://www.zerotier.com/. I've never had an external IP for home internet, so I always ran in headaches trying to do a home VPN to channel my internet traffic while I'm out and about (and that's why I use a VPN on a VPS for that).
