I'd say All-Star Superman has a very SJW feel, and it is an extremely entertaining story. The thing is, Superman is truly threatened by embodiments of bigotry, authoritarianism, envy, and selfishness. Indeed, he is mortally wounded by such early in the story. More importantly, those embodiments of evil are THREATENING PEOPLE OTHER THAN SUPERMAN, people Superman has to protect or they will be murdered/oppressed.
For a supposed SJW character, Riri sure doesn't fight any embodiments of evil. She just kind of gets into random fights with people who aren't threatening to do much of anything in particular.
Iron Heart is not a failure because she embodies liberal values. Iron Heart is a failure because her book lacks Eros and Thanotos. She loves nothing, and nothing she loves is ever in danger of dying.
Another aspect of a true SJW story is that the main character doesn't really face any real challenges, and those they face are easily overcome. That's certainly the case with Riri.
This is completely contrary to the traditions of superhero comics, in which the trope is usually that of a hero being beaten or embarrassed and having to rebuild themselves to come back and overcome a seemingly insurmountable obstacle.
Not so with Riri Williams, because her super power has repeatedly been shown to be brilliant at EVERYTHING, and so surmount all challenges with the utmost ease - afterall, to fail would mean that you are both sexist and racist!
