How can I become a more competitive applicant for universities?

Hi! Currently, I am a junior in high school. I am wondering how I can be a more competitive applicant for universities because I am a bit worried I don't have much to add.

Right now, these are my current activities/awards/classes:

1.) I got selected to participate in an 8-year rigorous and academic program with a 20% acceptance rate. (SEO (Sponsors for Educational Opportunity) I attend Saturday academies to further my knowledge and become a more competitive applicant through extra classes

2.) I received two awards from the program which was one growth mindset award and one dedication award.

3.) I was apart of Honor Society two times where I participated in taking a course with Cornell University and Arizona State University through NEON (National Education Opportunity Network) and scored in the top 20% nationally

4.) I have a Youtube channel that I started which is dedicated towards mental health where I plan, edit, and upload videos myself. Though, I haven't posted in a year which I plan on focusing.

5.) I took 5 dual enrollments but no AP's (due to several factors) However, I plan on taking two or three during my senior year.

6.) I participated in one summer internship and plan on continuing again this summer.

7.) I had my artwork featured in a museum cafe where I centered it on my resilience, identity, and passion.
