[DC] I’m a paraplegic speedster. What are some cool things I can do?

Closeup magic is the first thing that comes to mind. You'd be a world class sleight of hand artist after a few hours of research...

A custom engineered carbon fiber (or other suitable material) wheelchair might make supersonic ground travel a possibility, (stairs still a problem...)

If you had other skills to combine with your powers it would be helpful, you could be a speedforce Macgyver, improvising gizmos on demand with a backpack full of electronic parts... Or real time coding/hacking with a sufficiently powerful computer.

Edit: Wait! You could have foldable wings that anchor to your back and attach at the elbows... Flap your arms like a chicken and you can *fly*, bitch! You're ***The Hummingbird!***
