If down the road we need to share something between us, I can make a third VLAN and have it viewable by our two.
You could certainly make a third VLAN interface in pfSense and equivalent port on the switch. Then add firewall rules to allow both of you to access that new subnet. You could has a NAS device in that subnet to share files for example.
Depending on how you use your various devices you may want to have additional segregation. I have my wireless access point on a separate interface here at home for example. That way I can happily allow internet access to guests without worrying about what they may be carrying in their laptops. With that switch you could potentially have 7 isolated subnets.

Awesome, this will definitely open my setup up for lots of options. Thanks.
