Read up on various programs then apply around. Do you have geographic limitations? If you're not sure about academic vs community, then it's probably safer to go academic from an overall resources and connections standpoint. Any inklings about possible fellowships down the road? If you are thinking something uber-competitive like surg onc or peds, it's gonna be very helpful to have academic infrastructure to help you on that journey. Otherwise, I think you're gonna be just fine. Cheers.
