What ECs can I add to improve my profile in social sciences (specifically political) to get into Ivy League schools?

I'm a junior interested in going into the social sciences, I'm thinking of political science but I'm not 100% set on it yet. I think I have a pretty strong academic profile of 3.97 UWGPA, I'll have an Associate's Degree by the time I graduate high school, I've taken the hardest classes my school offers and done well in them fr the most part. Now I'm just focusing on raising my SAT score.

I know for a fact that I will get into my safety schools, but I would like to aim as high as I can (or at least get great scholarships at my safeties and targets).

I want to work on extracurriculars, right now I have 70+ hours of volunteering in the form of tutoring, PSIA training, teacher assisting, event organizing, fundraising, etc. I was also the head of marketing and PR for my school's MIST team, raising $2k+ in funds. I won 2nd place in social media and qualified for nationals at MIST, I began a student activism club (it's fairly new though, I wish I'd thought of it earlier), and I've been part of the student council all 3 years, I am the student council vice president, aiming for president next year. I'm part of a book club and I do videography/video editing and a bit of photography on the side, I have a couple of school/family/friends videos for that. I am fluent in Bengali and Arabic (reading too) with basic speaking skills in Urdu and Hindi and a bit of American Sign Language (although I sort of stopped ASL so I can focus on Urdu and Hindi). I enjoy learning about cultures and ties between multiple ones (I'm thinking of minoring in some sort of cultural study).

I would say I have a pretty good amount of extracurriculars but only the club is really centered on social science (I only gained interest in it this year). I think I might start a blog through the club. I also want to reach out to someone in the political sciences field like a legislator or a professor so I can intern for them or something but I do not know how to start it.

By aiming high, I mean I want to take chances and apply to a few prestigious schools and even an Ivy League or two. I'm looking at NYU (hard target), BU (target), Colgate (target), Rice (hard target), and then Harvard (reach) and Columbia (reach) for Ivy League.

Anyways, any other EC ideas would be helpful!

PSIA: Private Schools Interscholastic Association (I trained kids who participated)

MIST: Muslim Interscholastic Tournament (it's mainly for Muslims, but it's open to all nation-wide and in Canada)
