What are my chances at a mid to high tier UC?

I’m a high school senior and I have a UC GPA of 4.364 (I’m ranked #32/600 students at my high school) and my current SAT score is a 1450. I retook it and I would like to score higher (at least 1480). I would love to get into UC Berkeley or UCLA, however, the mid-tier UCs–such as UCI, UCSB, UC Davis, and UCSD–are all fine with me. How likely am I to get into at least one of these colleges? Also, by how much would I need to improve my SAT score from a 1450 in order to get into UC Berkeley?

Intended major?
Is your UC GPA listed the capped weighted or fully weighted GPA?
HS course rigor?
EC’s and awards?
