There are pros and cons to the location of the GFCI...a GFCI breaker is more expensive, but it will easily control everything you wire to it. Depending on how far away it is, it is usually more of a pain to reset it if it does ever get tripped (shouldn't happen, but certainly can). Having the GFCI device in the bathroom means, it is more visible and accessible, and you might actually test it periodically like you should, plus, if it does trip, you don't have to out in your birthday suit to reset it. Depending on where the things like light and fan are, they may or may not need to be fed from it. This means more planning to make sure you get the feed from either the line or the load side of the GFCI receptacle, should it be required. Some don't like the look of the GFCI, and a breaker can move it out of sight, as can a GFCI designed to fit into a wall box that may be more out of sight.
