I don't know about FreeBSD, but on Linux WireGuard yields some 15-20% better performance (on both throughput and latency). OpenVPN is completely crap. And both OpenVPN and IPsec are much harder to set up than WireGuard.

Assuming you're comparing to IPsec (and AES-NI accelerated AES-GCM on the P2s), and especially a routed IPsec (VTI) .vs the more normally found "policy-based" IPsec, then this isn't true, for at least 'throughput', and it's completely provable.
I've not tested latency.
Agreed with your statements on OpenVPN, and the advantages of setup for WireGuard .vs IPsec or OpenVPN.
