I think the difference is that for all those examples, my mind can instantly say "this universe has more advanced technology than we do" - and then, there we go, disbelief suspended. But with Falcon, he's doing something super human with the movie trying to tell us that he's NOT a super human.

But yes, then I just remind myself that no one is getting massive career-ending concussions either, and that obviously, in addition to more advanced technology, I also have to assume that the universe has more advanced basic humans. :P
