Suppose I add a firewall rule to my router to block traffic to a particular
port. Does my router thereby "wiretap" every packet passing through it
because it needs to find out its destination port in order to determine if
the rule applies or not?

It is sometimes a tricky issue when you filter through legitimate traffic to
stop illegitimate traffic. But a rule that this is always wiretapping of
anything subjected to the automated inspection leads to ridiculous results.
