Personal Investing and Compliance

I'll be joining a BB in the US this year within their IB practice and have a question re: personal investment holdings. My understanding is that individual stock picking is a major headache given compliance issues making it too much of a hassle. However, do index and sector ETFs have to be as tightly reported internally to the compliance team? I am most concerned about timing of getting my trade approved within my time frame when the opportunity presents itself.

Many thx in advance!
