It is pretty unusual to have a UC GPA that is higher than weighted GPA. You might want to double check here:

Assuming you’ve got it right, I think you’ll get into UCM, UCR, UCSC with a competent essay. A very solid application and/or improved test scores will probably get you into UCSB, UCD and UCI while I think UCSD, UCLA and UCB will be a stretch.
In the Cal Polies - I think you’ll make Pomona and not SLO.
I’d encourage you to look at LMU and USD - both privates that may throw some merit money your way.
As for your CC plan - since it sounds like you’d be targeting UCB/LA/SD. you should know that they don’t participate in TAG (transfer guarantee program). Making it in as a CS major will, likely require a 3.7+ GPA - a taller order than you’d think (for CS in particular). I’d encourage you to open your mind to heading straight to a school like UCSC just to avoid the transfer complexity, hassle and risk.
Good luck
