Contrast has more to do with lighting than camera settings I've found, but if you want more control over contrast shoot in RAW format which gives more control over things like contrast during editing.
A lot of cameras will also allow you to use custom pre-sets to adjust things like saturation, contrast and sharpness in camera. I've never used them though as I just shoot in manual all the time, so I cant tell how much of an effect they have.
