I could see you being an interesting combination of Monk/Thief/Soldier in a way...but overall I think I'm leaning more towards a White Mage vote as well (though looking at them more from the stance of characters such as Vanille, Leonora, Aerith, Penelo, Eiko, Aria, Sara Altney, and perhaps Refia since she can switch into that job class and is seen to be one in the FMV intro for FFIII). They tend to be rather optimistic, friendly, and stubborn characters at times who can be rather creative too (though it sometimes depends on the character and the situation they're facing). Many of them tend to be rather balanced in terms of their introverted/extroverted levels (Refia, Sara Altney, Aerith, Penelo, and Eiko especially), are rather cheerful for the most part, can lead but also be supportive when necessary, tend to be more modest overall (though sometimes they show a bit of confidence--such as Vanille's victory quote or Refia's, Sara's, Penelo's, and Eiko's actions at times), can be reserved at times but fairly impulsive in many situations (Aerith, Refia, Sara, Penelo, and Eiko are pretty good examples of this), and many of them can have rather energetic personalities too. I could see a few of the characters I mentioned possibly agreeing with your thoughts on group work as well, and your ideal career choices just seems like something a few of them would really resonate with too. :)

Yay for cute Oglops love and Curaga appreciation! :D
