Honestly the best thing the MCU can do right now is take an extended break. No shows, no movies, no video games. If you must, non canon animated shows like What If? Take three or so years off and start a new arching storyline off with proper development that lets audiences bond with a new central core of characters/actors organically, the way they did with the original Avengers. The post Endgame MCU has been such an unfocused mess. I haven't watched any of the shows or movies since Ms. Marvel outside of trying Secret Wars and not getting farther than one episode.
It's just hard to care when the wider narrative is so unfocused and half baked.
In a perfect world, absolutely.
Endgame was a great climax with some things left to wrap up (Guardians), after which it would do well with a good break/refuel.
Perhaps Disney/Marvel needed to hit their own "Snyderverse lows" to properly re-evaluate, but they never did. Just a gradual descent into mediocrity.
But with Discovery/DC relaunching their entire product, plus excellent Joker/Batman properties already in existence, there is just no snowball's chance in Disney/Marvel corporate hell that a bunch of stuff will not be forcefully pushed out to compete with it ASAP.
