I think in the case of Concorde JFK was preferred because the engines used loud afterburners during takeoff, climb and acceleration to supersonic speeds. For noise abatement they would takeoff on burners, immediately turn south to stay over Jamaica bay, turn the burners off as they crossed over the rockaways (populated barrier island south of JFK,) and then go back on burners over the ocean to finish climbing/accelerating. A plane like Boom that doesn't use afterburners could take off from any airport as long as they stay subsonic over populated areas.
