Credit the Russos with how they reintroduced (MCU) Peter Parker to audiences not just by introducing him in Avengers 2.5 Captain America Civil War, but directly associating him with RDJ's Tony Stark. Disney double-downed on that and had him connected to the hip with Ironman for the rest of RDJ's days, so everyone knew your most beloved MCU character considers this kid to be his protege and successor. In retrospect it was pretty smart.
Russos went a similar path with T'Challa and Steve Rogers. Not a protege relationship but an equal/mutual respect. Had them damn near deadlocked in nobility, foot-race, ability to whoop Bucky's ass, etc. but not done in a way where BP would show up Cap, or vice versa.
It probably would've made more sense to introduce Captain Marvel in Thor Ragnorak, and have her play off Thor and Hulk. Or alternatively in GotG2. Have her break bread with the OGs to build repore with audiences... and then she'd have been in a better situation to do similar for Ms Marvel.
