Middle school, bass or cello?

Hello everybody! I am in middle school right now and am a beginner trombonist. Next year, my electives will be advanced band and beginning orchestra. I have to make a decision though. I’m not sure if I want to play the bass or cello. They both seem really cool and each have their pros and cons, like for example, cello gets melody more often and I have multiple friends that play it, but there hasn’t been a bass at my school in 5 years and they play ton of genres of music. Thoughts??
