The goal of an attack like 9/11 isn't really to kill the maximum number of civilians in order to terrorize random people.
The attack had a significant degree of symbolism. The intended audience was twofold: the Western public and leadership, with a durable message that they weren't untouchable (hence the attacks on the Pentagon and attempt on the Capitol), hence targeting large landmarks; the combination of civilian and military targets was to signify that they held the two to he equivalent. Plans were actually presented to attack other targets that would lead to more casualties, notably a nuclear power plant.
The other goal was to incite a religious conflict from the Muslim world against the US, and therefore probably from the US against as many Muslim countries as possible.
So the primary goal really wasn't to kill as many random people as possible (though of course that was a consideration), it was actually to target the tallest buildings possible as well as the most important government institutions.
Unfortunately, it really did move the world in the direction they wanted. Despite being extremely evil, they actually were remarkably successful at causing the social and geopolitical changes they wanted given the resources they had, and that caused yet more damage we shouldn't ignore. It also bears remembering (especially today) that terrorists often and unfortunately aren't as dumb as we think, and we underestimate them and simplify their motives to our peril.
