I'm probably thinking of when she was Ms. Marvel which they'll probably be skipping to Cpt Marvel, but still. And yep, she was highly accomplished before powers, and part of that dynamic was that she was younger than most people to have become a major (likely in her mid-twenties) so that in itself was impressive to everybody. That's why a 35 year-old wouldn't work. And what if she's pre-powered in Infinity pt 1 but powered in pt 2? 'cause Feige said CM is an origin story, so i'm guessing the accident happens in between both movies.
