@Prescimone, Chris - Admin Thank you for your question.
In fact, Basic, Standard and HighPerformance are legacy VPN Gateway SKU. They are still working if you still have them, but you can't create a new VPN Gateway using those SKU beside of the Basic. Below, you have the new SKU: https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpn-gateway-settings#benchmark
A Policy Based connection is only supported by the Basic SKU. You can use a Route Based VPN Gateway, and still customize the connection for your policy.
