I mean, where they're at with the Avengers it's best to just back off the property for a solid bit of time. None of the characters are compelling or feel like they've earned anything.
Captain Marvel was/is mediocre and has been made OP with no flaws and little to nothing interesting about the character, Shuri as black panther is meh, Shang Chi is meh, She Hulk is meh, I dig Falcon but he's a supporting guy imo and not a tent pole guy, the Scott Lang ant man is fine but just fine. Not sure that nearly 60 yr old Don Cheadle is a guy to hang 10 years of carrying future movies on, though he's solid as Rhodey...but again, another supporting guy.
Take a step back, focus on Xmen being a thing (also allows marvel developers to treat the MCU as if it's not quite there all the time....there's no reason for the Avengers to save the day regarding Mutant threats they have no way of knowing about...allows you to tell stories within the same world without dragging the same characters out again). Cast well (like they did for phase 1-2), tell good stories again, slow build to your big baddie Sentinels...try to forget that the Eternals ever happened.
