@Josh Rich, first off welcome to the journey. It's long, almost never predictable, and takes occasional grit to press on, but the rewards are worth it! I can't speak to all of the areas you're interested in, but I would suggest that you ask yourself what your ultimate goals are and then work backward from there. And be specific.
Going the corporate route and working for a company is certainly an option. As one who used to work in finance, I would caution about getting stuck in a position where you are making good money but are unable to find the time or push hard enough to put real hours in on your personal real estate endeavors. Having a flexible job with enough fat to save and invest is arguably a better position to be in for what it sounds like you want to do.
If you do work for someone, I would suggest a much smaller venture, where you are able to wear many hats. I would bet that more often than not, you also have more flexibility as well.
Also, while I don't have experience finding a mentor (mine is my Dad), a good mentor is INVALUABLE. I'm twice as experienced in the business as my years because of all the wisdom I've received without having to fail to get it. (Trust me though, I've still made and learned from plenty of mistakes.)
Keep in mind that, as with many other things, the key to getting where you want to be is to just do it! Want to get into MFR management? Find an MFR manager and work for them, even if it's for peanuts...
