OP is a California resident who applied to several UCs and a few CSUs as well (with good in-state financial aid and strong engineering degree programs). So it is extremely unlikely for the OP to be completely shut out of four year schools. Even if the OP does start at community college (not likely), the transfer pathway starting in community college is well developed and well used in California. I.e. it is not like the state university and community college options are useless or unaffordable like in some other states.
“Fit” includes academics… the OP’s original list included Dartmouth, which is not particularly good for engineering majors (need >4 years for the ABET-accredited degree).
