F500 Financial Analyst Internship vs. Middle Office Internship at PWM/Regional Superbank

Wanted to get some advice on this. Trying to decide where to intern this summer.

On one hand, I could intern at a F500 and receive a potential job offer upon graduation that's pretty appealing (this particular company promotes to SFA/Manager pretty quickly and the pay is 100K range pretty soon after school). However, I'm less than optimistic about this particular company in the long-run because it's probably going to get obliterated by a combination of Amazon/Walmart/other retailers pretty soon. The experience as a FA intern would probably serve me pretty well for positions at other F500 companies I imagine, and there are a lot where I live.

On the other hand, I got an offer to do Investment Operations work for a PWM/Regional Superbank. I wouldn't want to work for them out of school because the pay is pretty poor in comparison, but my advisor said it looks better on a resume because it's more selective and it's easier to jump from banking to corporate finance than the other way around. Still, I'm not ecstatic about middle office (probably a lot closer to back office if I'm being generous) because I have no aspiration to be an IBer or do PE/HF. Would this help to get into a high-tier graduate school down the road? Several people I know that worked as Analysts and Account Managers and went on to get into Booth, Kelley, and Kellogg.

As for ideal career path, consulting would have been my ideal but I struck out on my B4 superday. Still, the hours and work-life balance with good pay in corporate finance appeals to me. On an internship perspective, would it still be better to go with the IO internship?

Appreciate any perspectives.
