The problem with this is that "fight scenes" is a category as broad as old Macdonald's farm.
You can do it like Monthy Python, and make it a completely rediculous and unrealistic comedy skit, like the black knight scene for example. You can do it like your stereotype american war movies and make it extremely dramatic, and focus all your characters getting PTSD. Or you can give it a more "life goes on" perspective, and focus on how things can happen very quickly, but that, whatever happends, the things that need doing still need to be done. And ETC.
There's not a right or a wrong way to do it. You do it in the way that you want your story to come out.
Best indeed is to follow up on Wz's advice, and just see if you can find a few examples that fit your style...
