unifi-pfsense VS PIA-NextGen-PortForwarding

These definitely support VLANs, as well as many other features. They do require an application for management installed on your network, although this application does not have to be left running unless using a captive portal on a guest network. That being said though, there is a GIT hub project that allows you to actually host the controller ON your pfSense firewall. You can find it HERE.

or install it on the pfsense box https://github.com/unofficial-unifi/unifi-pfsense

May not be applicable in your case, but I run my controller instance on my pfSense firewall. There is a well support GitHub project for it HERE.

For the past couple of weeks I've been using this using the UniFi controller installed by the script from here: https://github.com/unofficial-unifi/unifi-pfsense

That’s what I use, an AC-Lite, USW-8 150W, and USW flex mini. UniFi on pfsense with this script: https://github.com/unofficial-unifi/unifi-pfsense

If you are very (I mean very extremely) adventerous, you could check this insanity on GitHub: https://github.com/unofficial-unifi/unifi-pfsense

This will help you, but I've not tested it personally. https://github.com/fm407/PIA-NextGen-PortForwarding

My understanding is that I need to use a PIA server that supports Port Forwarding, I am using one per this link: https://github.com/fm407/PIA-NextGen-PortForwarding/blob/master/nextgen-portforward-servers.txt
