I think the direction you've steered the thread is a pretty natural shift. The points you've personally made are spot on. So much so that the folks that reimagined her weren't shy about addressing the elephant in the room.

"As Ms. Marvel and Captain Marvel, Carol has led the Avengers, adventured with the X-Men and saved the world over and over again. She’s one of the most powerful Marvel superheroes who isn’t simply a god.
And in the MCU, where characters like Storm and Jean Grey don’t (yet) exist, she’s inarguably the most powerful superheroine around."
This piece cannot be overlooked. Carol occupies the space she does in the MCU by default, not because it's what her character deserves. The people responsible for bringing her closer to a real world heroine acknowledge this willingly. This isn't about putting two women against one another for the top whatever spot. This is about simply acknowledging what is. Carol is toted as the most powerful woman or hero in the MCU because Ororo and Jean aren't available to contest her place. That is calling a spade a spade. Its always kinda weird as these conversations unfold because of the "stop pitting women against each other" vibe that comes along. From my pov the really important part never gets addressed. It's always a variation on the same conversation.
While we sit and debate why Brie Larson's Captain Marvel deserves a place in the MCU, the quote directly informs why she doesn't deserve the place she was given. It's no different from the Avengers having their given place because the X-Men were unavailable. Brie Larson and her portrayal of Captain Marvel as far as the feminist agenda goes, falls on the deaf ears of the black women she had to step on to get to her place of personified white femininity. Not only was the name Captain Marvel taken from Monica Rambeau and given to Carol Danvers so she could run around and build a reputation as the most powerful marvel hero on the scene. Monica dwarfs her, but she was nerfed to make her more human in a time when women are supposedly evening out the power dynamic.
Then we have Storm that's clearly more deserving of the spot as Marvel's premiere heroine because of what she represents. For everything that Carol represents, Ororo represents and more. White feminists and black feminists often don't see eye to eye because black women have always had a contentious relationship with mainstream femininity. Their's has always been denied. The darker the black woman, the more likely she is to be denied her feminine nature. The courser her hair is, the greater the likelihood she will be denied the shield that mainstream feminist agendas afford white "women". When feminism was getting its first push for "women" to enter the workforce and get out of the kitchen, it was black women that were being cooks and nannies. Black and white women have never been in the position to want for the same things. Black women are still fighting for their rights to be feminine all while pictures have been painted for decades of black women too masculine and therefore deserving of the brutality committed against them. White women have been complicit in their silence. The only time a slave woman's femininity was brought up was when the eyes of the slave master fell upon her body in lustful ways. Other than that, black women had the same work load as black men.
None of this means Carol isn't deserving of her own place in the MCU. It means she isn't qualified enough for the place she occupies now. She was given her place over two black women that embody everything she does and more. The worst part is we're expected to believe that she inspired two women of color to take up her brand of superhero business. I would say I'm surprised if the same thing didn't happen with Fox's Storm and Mystique's farce of a dynamic. Why do white women love to use their brand of white supremacy to deny black women their rights as women? And why is it such common place for people to ignore it?
