Trust me, Pocahontas is a mature ENFP. She is random, flits about, people never know where she is but they do like her, she follows her heart, instead of standing by her tribe as she is supposed to and her whole fascination with the people coming to her land reeks of Ne-curiosity, allowing her to see both angles, both povs of the conflicting parties and allowing her to broker a peace.
'Colours of the wind' demonstrates both her Fi and her Ne. She demonstrates understanding what John Smith has told her about his land however foreign it is, and calls him on not showing the same respect in return. She opens his eyes to what their way of life is like and what it has to offer, how to look upon her land as more than something to butcher and sell off, but to value it for what it is now, while still untouched.
If that aint NeFi, I dunno what is
Even when things fall apart, the self-doubt, the guilt for following her heart instead of being a loyal daughter, for not acting sooner, to then re-assert herself to even her father in what she believes...
Compare her to Esmeralda, who stands by her tribe and stands up for her people against injustice and plays the crowd to stand by her. Pocahontas does not have her tribe on her side, quite on the contrary. Esmeralda is a platform for her people to speak out on, where Pocahontas is a a bridge build between two people.
