[Late, sorry]

I have been playing around with that, for the purpose of *outgoing*
filtering (squidguard). It basically works out of the box, captive on
http but not https.

You'll want squid 3.4+ for https filtering. As everything is becoming
https this is going to be the new normal. You don't need to break the
ssl connection by setting squid up as MITM (although it is capable of
doing that, pfsense even has it in its BUI), you can set squidguard on
the CONNECT host name. Only the host name though, squidguard URLs are
ignored / don't match on https then.

Ensure you use the latest pfsense, all others are insecure.

Squid and squidguard on pfsense are trivial to get going. Unfortunately
the BUI for both is IMHO fairly bad. You may hack into the pfsense php
(easy) for config tuning. I am not at all impressed that pfsense
switches to "allow all" when squid or squidguard go down (not so
difficult with bad configs)!

Also, running a service like squid on your firewall is not really the
done thing. It does run on a PCEngines APU board nicely, but be wary of
SSDs for the squid cache...

Squid is also active for the wifi AP connected to the pfsense box
externally.

HTH,
