The problem with open-ended questions on a forum like this is that without clues as to the original poster's knowledge base, it is hard to know how in-depth to focus the response to best answer the question.
I would say that if you are trying to place limits on your time at work in order to have more "protected time" for family, you will need to think especially carefully about your practice setting. While you may be able to sign a lucrative contract as a junior associate at a smallish practice with a large catchment, you will almost invariably end up working some long hours in your early years to protect the practice's bottom line. Conversely, practices strongly affiliated with a university tend to pay less (often a lot less), but may be able to offer you some additional time-flexibility, research time, etc because the university focus is slightly less entreprenurial. This has implications for your choice of fellowship as well, as there are some fairly ambitious multi-year fellowships for academic types who are more interested in a tenure track, vs. single year fellowships with an eye toward private practice.
I doubt that the money will ultimately be an issue for you, but time balance may.
