With fictional ENTPs and/or 7s, I wouldn't quite describe it as "looking up to" necessarily, but I'd love to hang out with them if they were real people. I really vibe with Tyrion Lannister from GoT (I'm gonna pretend GRRM isn't taking his sweet-ass time with the books and the last season never happened); he really experienced a more positive trajectory away from his negative past and struggles with his family at a certain point in the series. I'm very drawn to characters who experience moral arcs for the better; self-discovery and self-improvement are two areas I'm really fascinated by and good at assessing for myself, but it's a lot more difficult for me to make progress. Sokka from ATLA fits this bill for me (he's a 6w7, but still). Also, Ian Malcolm from Jurassic Park and Tony Stark.
In real life...a lot of ENTP politicians are less than pleasant, so not sure I'd want to emulate or draw inspiration them, haha. Also, Elon Musk has been classified as an ENTP, I think? Smart guy, but not someone I'd want to be like. I really admire a lot of polymath-type figures I'd classify as ENTP (ibn Battuta, Leonardo da Vinci come to mind); I'd want their intellect and the journeys they had. I think I'm just as drawn to historical figures with complementary traits and cognitive functions as I am of my own personality (particularly Fe-doms and certain ENTJs).
