Bard is the most utility driven DPS, it has tons of songs and stuff that contribute to utility.
Ninja is the most utility driven of the melee DPS, it has trick attack, a dps buff, and some aggro management tools.
Red Mage is great at progs with progression/heals/revives in raids and in some of the newer content like HoH and Eureka.

That's just DPS. Really every job has a "niche" utility unless your Black Mage or Samurai. If you want quick queues go tank, a bit more complexity healer.
