I'm guessing WireGuard PSK is post quantum safe, because it doesn't depend on a private/public keypair?

Could you please explain what does it mean in PSK context? Any relevant link.

If you pre share symmetric keys, you are only dependent on symmetric keys. Symmetric key cryptography is mostly quantum safe already, although you may need to double your key size.
