Warrior, Thief, White Mage, Black Mage is one of the two most common teams. The other being replace the Thief with the Black Belt or Monk or whatever it's called in your version. It's a perfectly good team.

Me however? I prefer physical attacks, especially in the DoS version because all the good spells can be cast from items. And as much as having two of one character can be great, I prefer not to. Therefore my "favorite" party is Warrior, Thief, Black Belt, Red Mage. I just like having different characters, and magic is really not important in FFI. You run out way too fast, and by the time you really "need" it to help out, items can cast them.
