I just want to riff on the bolded. I think Marvel has a much greater negative societal influence than you acknowledge here. The reason is that it mostly influences the worldview of kids when they are malleable. We haven't fully seen the long-term negative impact but I think it greatly contributes to America's general mindset on guns. It 100% reinforces the whole "good guy with guns" narrative by consistently presenting the audience with the view that there are big bad evil people and the only thing to stop those big bad evil people are good guys that are heavily armed (with superpowers). They completely overlook any sort of institutional reform or collective means of problem-solving for this whole charismatic superhero as the solution narrative. It reinforces these cognitive frames way before people grow old enough to vote. It's essentially training kids to accept many of the narratives you hear from the worst of the conservative politicians.
Wanton destruction and in the next movie everything is rebuilt and the casualties and even daily stresses of the average person are overlooked, completely shoved into the background, because the effects on the average person are ultimately unimportant. The narratives in Marvel movies craft a worldview where people don't have to think because the superhero will save them. We can see variations of this exact mindset in Trump and his followers. How they idolize him like he is a superhero because he is rich. In many ways, Marvel movies train these people that become mindless Trump (or Elon Musk) fanatics. It removes a nuanced way of viewing how the world works.
There have been some comic books that actually deconstruct this phenomenon and essentially portray what the world would really look like if people had superpowers and it wouldn't be anything like Marvel movies.
Miracleman: The Golden Age from Neil Gaiman is one that is remarkable in pulling back this curtain and examining what the superhero narratives really mean.
