Cornell is open that legacy is only a bump in ED. Not sure about NU but my D’s friend, a legacy, was rejected a few cycles back with stronger grades and scores.
IMO, these are really reachy schools for everyone but especially with a lower GPA (and you can easily calculate your UW GPA yourself).
Be sure you have match and safety schools on your list that you would be happy to attend. Are you applying to GWU and American? Those come to mind right away in reading your profile.
Your strong upward grade trend will be attractive to any number of schools.
