To be clear: your metrics will not impede you from getting attention at any of the schools you target, including the UC schools. The challenge is articulating your purpose and mission fit with the school through your activities, which include baseline expectations. Service orientation activities serve as a way to separate high-metrics applicants and determine mission alignment. I don't think your 450 hours of food bank work will be a big problem, but now it's a question of how that matters to your purpose as a physician.
Campus/event EMT Is fine, but you should graduate to working community EMT where you have a broader variety of potential patients in the contexts of their home communities. Community EMT will give you greater value.
It's fine if you categorize these activities in AMCAS as non-clinical. However, screeners and adcoms can tag/recategorize your activities to measure your mission alignment/fit with their programs. With your metrics, you should have the 250 needed to stay on pace with most applicants, but if your mission focuses on "underserved communities," you need more coherence among your activities. It could seem a bit random, though I credit you with hitting as many members of a community generationally as you can.
Remember that medical school involves you living among those in need. What is it about NYC that your current activities can help prepare you for at Einstein, NYU, Columbia, Cornell, Sinai; do you want to attend them all because they all offer work with very similar populations? What's the difference? Two of them offer no tuition, so it's not just about cost.
