The feeling is that Carol Danvers will be playing a major role in the future of the MCU, but we didn’t really get that idea from Avengers: Endgame.
Captain Marvel is one of the more interesting characters in the MCU right now simply by virtue of how new she is.

She’s clearly powerful, but that’s about all we can say with certainty.
