It's either that or ISFP. He shows both strong Se (he's a Chuck Yeager and a decently apt mechanic like his daddy) and Ni (his dream to fly the galaxy as part of the rebel alliance). He just seems more Fe than Fi to me.
I don't think Luke is Fe-dominant at all.. he's very value-oriented.
His dream to fly the galaxy could also be Ne or tertiary Ni.. what I'm saying is that I think he's an ISFP and definitely not an ENFJ.
