You haven’t answered blossom’s question about what school will make it easier for you. And a soph summer internship isn’t nearly as important as the one after junior year.
If you want to transfer now, your HS record will still be an important piece of the admissions decision.
What is your budget?
With that said, do LACs appeal? If so, look at Trinity and Connecticut College. I think BC and Colgate could make sense, but both are reaches. If you are certain you want to transfer you will also need an affordable safety. Marist does well placing students in banking and finance in NYC, and would probably be a highly likely admit for you.
Good luck.
