Summer Job vs Summer Camp vs Volunteering

Hi! I am a freshman (9th grader) in high school and I don’t know what I should do over the summer. I have about 50 volunteering hours so far and I plan on earning more. I volunteer at the animal shelter. I will be doing that this summer. As far as the summers that will come later I don’t know what to do then. Is it better to get a job, go to a pre college camp at like Duke or volunteer? What would colleges prefer? I don’t really have a preference. The only thing is what if I don’t get into any college camps.

Oh and also, I am going to go to an engineering camp this summer at University of Houston.
