Some time ago someone wrote a piece about the difference between SW and ST being about narratives of personal power; essentially SW usually hinges on a "chosen one" plot and special abilities vs. ST essentially being competence porn, where it's always about someone working really hard to get where they are. In ST power is essentially shared governance, and a lot of Kirk's (and Picard's and Sisko's) preoccupation with command comes from their desire to do the best for the community ("The needs of the many" etc.) in a way that SW just isn't (even the good guys have a blurry relationship between the Republic and the Resistance, let alone the Empire and--my favorite from the prequels--the elected monarchy and the familial Senatorial rank). TL;DR SW is about special people and ST is about how everyone can be special. >_>
