@wardex Hello, thank you for this information. I am confused by:

This does not work well when you have a load balanced Gateway Group set as the default Gateway Group in System/Routing/, but does work in policy routing when you set a Gateway Group in your firewall rules.
My default gateway is still listed as my WAN. Under the settings, default gateway says automatic. Do I need to change this? I am not using the WAN gateway in any of my firewall rules.
It should be fine, the main point was that if you wanted to load balance your VPN's using a Gateway group as the default wouldn't be the best choice, but policy routing through the firewall, as you are doing, is better. It mentions this in the pfsense manual.

Further, you could even split those tiers in your policy routing Gateway Group, so for example, if you had six Proton gateways, two could be on tier 1 and two could be on tier 2, and two could be on tier 3.
This would round robin the two tier 1 gateways until they were down which would failover to the two tier 2 gateways which would be round robined, and so on.
I don't understand what would be the benefit of this over having six gateways in one group. Would the benefit by faster switching when one goes down?
You still have the six gateways in the same Gateway Group. The difference is tier 1 will load balance between the tunnels until all tier 1 tunnels go down then pfsense will switch to the tier 2 tunnels (failsafe) and load balance those tunnels, and so on. You may have four Seattle tunnels on tier 1 and two L.A. tunnels on tier 2 , and may choose to load balance the Seattle tunnels, as they may be your preferred tunnels, but if they all go down pfsense will failsafe to tier 2 and load balance the L.A. tunnels.
It gives you more control but the tier 2 and subsequent tiers will usually see less action than the tier 1 tunnels.
Maybe you prefer P type tunnels in one city but there are only two of those tunnels and the rest are p2p tunnels. You could put the two P type tunnels on tier 1 and four p2p type tunnels on tier 2 for failsafe.
