Dilemma on what to pick for Junior Year Internship

I currently have two offers for my Junior year. I have an offer to do TAS at a boutique accounting firm that does TAS  primarily for search funds. This offer expires tomorrow. I also have an offer for a F500 retailer for corporate finance. The Fortune 500 retailer is a big notable company but they don't have an FLDP and pay seems kinda shitty. They didn't convince me to much on growth opportunities. This offer expires next Monday. I had a final round interview for a boutique investment bank that I would take over both of these in a heartbeat and I was told I would hear back later this week. I am also in the process with a very large F50 company with a more reputable corp finance program. I also will be hearing back from another F500 with an LDP this week from a final round. I recruited for banking this spring, summer, and fall and got fucked. I Had 7 super days and couldn't convert. Im not sure if I want to do banking full-time. I am ready to give up and join the ranks in corporate Finance but I'm not sure if I should accept the TAS internship or wait and use the f500 as a backup if I don't get any of the other offers this week. Any advice on what to do? I could also just start accepting and reneging but these places have connections with my school and I don't want to start getting into issues.
