The only way I see Bourne being metahuman is his durability/endurance. Falling multiple stories, surviving car bombs and walking out of epic car crashes moments after, and his last feat, surviving a fall into a lake from the top of a building is beyond what any normal human (peak) could do imo.
Also, I'm convinced no normal human could be as smart as him in his situation, although its very subjective what is or isn't metahuman here. I mean throughout the whole film, he is on the move, fighting people, evading being captured, and all the while he is still a calculating machine every second of it, knowing exactly what he intends to next as well as having a larger overall plan. Pretty much 'prep time', but without the 'time' lol.
As for Hitman, I would say his skill and coordination is metahuman with the 4km sniper shot.
