This is to one side of the point - many historians hold that the U.S. was keen to demonstrate the power of these bombs in order to cow the U.S.S.R., (and prove they were practical) even if it meant delaying the end of the war.

Firebombing was even more effective (but not economical) in killing Japanese civilians, as you note. However, firebombing would not have been as effective vs the Soviets (far less flimsy, compact wood construction) nor have the same effect vs ground forces: making a live demonstration of atomic bombs still useful intimidation, according to this view.

Besides cowing the USSR, I think that a valid war aim was fully cowing Japan.

One of the lessons of WWI was that military victory wasn't enough, too many Germans could tell themselves afterwards that they were stabbed in the back, etc. If the goal was to defeat Japanese fascism, then it was important that no Japanese could believe such things afterwards. And for this, a shocking weapon (one plane, one city) was effective in a way that (say) a starvation blockade would not have been.
