Your scores and GPA are obviously great for any of these schools. Your list of EC’s is extensive but, as noted in the comment above, doesn’t have remarkable depth in any one concentration. That’s important for Oxbridge, but also for top American universities as well. I’d say:
Stanford: Reject
Oxford/Cambridge: Reject
UChicago: Waitlist
Cornell: Accept
UCB: Accept
UCLA: Accept
UCD: Accept
Best of luck!
