To be clear this is which Marvel and Avengers related characters you'd like to see, even if it's just a small cameo. Personally, The Falcon and/or Black Panther. Both of African decent, they'd bring some (in my opinion) much needed ethnic diversity to the team. (Black Widow doesn't count, and I'm sure they'll sideline Col. Fury). Back-up choice would go to Jimmy Woo from Earth 9904 just because he's an F.B.I. agent.
To expand on Black Widow, the reason she doesn't count is because she only sounds different. She still looks "Western".
