I was honored to receive a type 1 this year, I had a 33 ACT and 4.33 GPA, so very similar academically to you. Also a student pilot, won't be able to afford full PPL however. Fitness score was a 10:10 1.5 mile, 55 pushups, sit-ups somewhere in the 60s I believe, and I have a 30 inch wait 145 pounds. You can calculate the points for that if you want to compare.
I would be sure to find plenty of leadership positions and service as this is where I felt my applications stood out. To list a few I was the cadet commander of my civil air patrol squadron that year, national honors society staff, search and rescue team member as well as SAR instructor in CAP, and I had several community service experiences (3x Gold PVSA)
Probably the most important thing to remember is that if you are qualified for a scholarship, I have heard that 75 percent of the points you are given comes from your interview and largely determines what type you will get. Mine laster an hour and 20 minutes, the first section was him explaining the program. If you have done your research this part will go well, not knowing the basics of ROTC or the core values / etc won't look good. Additionally, this is a great time to ask questions, which will come across better if you already have some basic knowledge.
The second part will be where you are asked many questions, some sounding almost the same. If you only have one or two things to tie in to your answers then it will be monotonous for you and the interviewer, not good. My interview was very insistent about wanting specific responses to answers, avoid giving vague cliche responses, they get those all day long. If you have several things you have been heavily involved in that you can tie in to your answers it will be an interesting interview and you will actually have something to talk about with your interviewer. Search and Rescue was an incredible talking point as there are many similarities with the military there. He also seemed to appreciate the fact that I was interested in what he had done for a career and learning about other career opportunities than my plan A. He asked what I would do if I could become a pilot, what I would do if plan B failed, and would I be ok running a maintenance devision or being a logistics officer. If you don't realize the importance of those careers then it is difficult to answer that question confidently.
Also, you will be asked questions about times you have worked with a diverse people group and things along those lines. Don't BS your way through those, they actually do care and it is highly applicable to the military.
Think ahead of time about conflicts and failures, everyone has their good times on the top of your head, but you have to think about challenging times and how you overcame and learned from them, difficult to do on the spot.
Best of luck!
