Northeastern waives application fees for lots of students - it’s a marketing trick to increase the number of applicants, and not an indication that they are a safety.
CWRU is not a safety either.
IMO, the potential “highly likely” schools on your list are Rutgers and Ohio State. I’m not familiar with UC Irvine or Davis, so I can’t comment on those. I don’t think any of the other schools are safeties for CS.
