Do I reneg for an IB internship?

I'm a sophomore.

Option 1: Already accepted a corporate banking role at a bulge bracket. It is in a regional office. I am from there, so I would save a lot on rent by being with my parents. 

Option 2: Foreign bank that is very small in the US but a bigger deal in Europe. NY role where I would have some exposure to IB. It is growing, supposedly, and it is true banking (levfin, M&A, DCM, & ECM). 

Option 3: Sit on my already accepted offer and wait for something else to come in, like UBS's sophomore analyst position (and reneg only if I get something incredible like that).

I don't entirely know what I want to do in my future. CB seems cool b/c the work-life balance and the pay, but I want to keep my options open. For that reason I'm looking to IB--I have options. 

I have already submitted some SA 2023 apps, namely to RBC (I can't believe they open so early!), and to some sophomore insight programs (not as big a deal). I told my school's career office I would be taking the CB offer, but I didn't get it through them and I only went to them when asking for advice on whether to take it. 

Obviously I don't want to get blacklisted from a bulge bracket, but I don't really care about offending the company as an entity. I do care about the people who decided to take me as their intern--they seem nice! The last people I want to offend are the career services people at my school. 

So, which option do I follow? If I had to decide right now I would stick with the CB, but I am leaning towards the foreign bank as it is true IB. Share your thoughts.
