Well, that's thinking ahead some. You can basically use whatever weapon type you want, but remember that a Mercenary Mod will be less useful if you don't primarily use SMGs. It's partially for proficiency, partially to get the feel of the weapon type. Anyways, if you want a Firefly build, remember that the Hellfire SMG is probably the best weapon for that sort of build. There are others, however: the Volcano (sniper), Firehawk (pistol), or Draco (machine gun). Basically, you'll probably just want incendiary weapons. Don't forget that SMGs tend to be the best elemental weapons, however.
