I don't think you should put too much emphasis on the film, but more development equal more separation between the high end of the gray scale and the low end of the gray scale, true for any film/dev combo-----but mind your important textural high values that you don't lose them with too much development. Play with dilutions, and a film/dev combo with a longer toe and a somewhat steeper rise in the curve through Zones V, VI, VII, and VIII as in TMX and TXP developed in HC-110 will provide more inherent contrast, at least in my experience. But also remember the inherent contrast of the scene too, regardless of film and dev, on a gray day, shadows will contain much more diffuse light. So to create more separation from the low end of the scale from the high end, reduce exposure to the shadows and bump up the development time and that will introduce more contrast to the negative as well.
