You are a strong candidate- but I’d move all your UC’s (except Riverside and probably Santa Cruz) down to the reach category. Check out this year’s admissions threads and you’ll see students with stronger profiles denied from UCD, UCSB, and UCSD.
Don’t start or do things just for an app - do what you enjoy.
And echo that if your parents won’t pay don’t apply ED. It’s only going to cause a lot of stress this time next year.
Good luck!
