WTF are they doing to you guys over there?! Do you happen to know if Spectrum uses or recently switched to CG-NAT? Even if it's not CG-NAT I'd really reconsider WG given the ISP nonsense. Tailscale, AstroWarp, NetBird would take all that bollocks out of the equation for you.
(Be aware those SDNs aren't post-quantum cipher based should that matter to you but neither is WG without ensuring a PSK in its per-file conf)
