Setup for trunk via OPT1 port of SG-3100

You would need to use tagging to break out vlans into your network.. For the switch ports I am not sure if you can break them out in a port mode or have to use them with tagging to make them discrete to be 100% honest.. While I have 2 3100s I have not had need to break out any of the switch ports to other vlans as of yet.. Just using the as switch ports for lan and currently both devices only have switch connected to 1 port that vlan is on..
I count 5 networks there.. Your lan which is default on the switch I believe could all be on the switch ports if you have devices directly connected.
Then 1 of your other networks could be untagged on your opt1 interface 3 of your vlans tagged. Or they could all be tagged - that is up to you.
Only reason I could see breaking up the switch ports into their own interfaces is if need more speed between vlans for intervlan traffic. Keep in mind every vlan you put on a physical interface will be sharing the physical bandwidth of that port.
Do you plan on connecting any devices directly to the switch ports of your 3100... Will these devices need to be in different vlans? Will you be connecting an AP directly into one of these switch ports that will carry multiple vlans?

This seems overly complicated. Let the Ubi switch do switching (vlans) and let the pfsense do routing. Can you hookup everything to the Ubi switch instead?
Then, you only need 1 cable on the sg3100 lan to the switch. Put all vlans in that (trunk) port. LAN configs between the sg3100 & switch should then match.
Just my $0.02.
