The first thing I think of is weight of the jig, then trailer size. How fast of a fall rate do I want? All that depends on what kind of cover I'm targeting. Docks, shallow wood, or deep gravel? The there's seasonality - I've had good luck with a 5/16 oz jig on pre-spawn fish, but once the spawn is done I'll hardly ever fish that small of a jig. So many variables, best to be flexible and adjust to conditions, IMO. As far as color, I like green pumpkin (with maybe a little orange or purple), War Eagles Pond Scum Perch, and black/blue.
