Wireguard protocol only supports public key auth by default so it’s not really designed as a corporate style vpn where you have multiple people logging in from roaming laptops and authenticating with their own personal LDAP/OTP credentials.

I’m also not sure if wireguard includes any capability to setup network routes or if that is another thing you have to DIY or find a separate tool to handle. Openvpn, with its much larger code base, includes all of that plus the kitchen sink. You can hook directly into PAM auth to use your favourite OTP plugin very easily.

The same cipher list can be achieved in openvpn via configuration but wireguard makes it easy by not even giving the choice of older crypto. I guess being a newer protocol allows such liberties to be taken.

I can’t really answer that one. A VPN doesn’t always guarantee privacy as that is entirely dependent on the security and privacy of the vpn endpoint that you are connecting to. Maybe Tor is useful for that but I can’t say much as I’ve never used it.

Hopefully someone else here has more guidance.
