Thanks Pablo. Good to have in case we ever move to an HA setup with Google VPN. For anyone else that reads this, my posts were for the Classic Google VPN setup (non HA).

One note I wanted to add, in the BGP settings in my instructions above, don't change the setting for "Redistribute connected networks" to Yes. When set to Yes this advertised our WAN network to Google and caused issues with hitting public facing servers we had in Google. Since we only have a few networks locally, I just manually defined those along with the BGP network in the fields below that setting.

The other option may be to change the setting to Yes and somehow mark it to ignore the WAN network, but I haven't looked into that.
