https://en.wikipedia.org/wiki/Transmission_Control_Protocol#Connection_establishment should be a good start. The Protocol Operation section would be a good place to focus.
for example, TCP:PA would be be a "push ack" , TCP:FA would be a "FIN ACK", etc…

The basic list is always shown at the bottom of the firewall logs.
It's also on the doc wiki: https://doc.pfsense.org/index.php/What_are_TCP_Flags
