Some more thoughts from when I talked to a friend.
I had noticed how T'Challa was like the perfect Starlord, maybe a little too perfect. And of course Peter ends up being a janitor.
There's another angle to that, within what they showed us. T'Challa came from privilege. Rich kid, good education, great parental role models, and an instilled sense of duty.
Peter did not. He was literally an at-risk kid, picked up by criminals.

After seeing the Eternals trailer, there's another twist. That movie won't happen in T'Challa Starlord's reality. I think that episode canceled more movies than Captain Carter.
