[MCU] How powerful/skillful is Shang-Chi?

I don’t think I really understand how good this guy’s power set is. He has no super powers but is really good at fighting. 

I imagine he’s under Hawkeye and Black Widow in the rankings. Hawkeye casually went around the world in Endgame and eliminated dozens and dozens of organized crime members easily. He fought powerful drones in Sokovia. Black Widow fought aliens in the avengers and her cardio barely took a hit. She was able to survive a fight against the Winter Soldier. How can Shang-chi compete against this? It doesn’t even look like he has good tech to use like Hawkeye or even Black Widow.

If you took Shang-Chi and dropped him in Civil War, would he be able to tip the scale in favour of Cap’s or Ironman’s team if he fought for either of them? I really don’t see him being able to go toe to toe with anyone in Civil War except for maybe Sharon Carter.

Is there more to this guy than just being really good at Kung fu? It’s not a knock on the character, I’m just having trouble seeing where he fits in.

He is considered probably the best martial artist on Marvel’s earth and has mastered virtually any hand-to-hand combat form you can name. Black Panther believes him to be better than Iron Fist. Pretty sure he also trained Spider Man how to be an effective martial artist- Spider Man, a guy with perfect reflexes and superhuman strength, took pointers from him. His day job is basically helping MI6 beat up criminal syndicates. 

You know how Bruce Lee has that memetic God status among his disciples? Shang-Chi is basically that status made flesh.
