I was charged with possession of marijuana and possession of paraphernalia in Florida?

I am over 18 yrs old and this is my first offense ever. was caught with literally shake (less than a gram) and a pipe in my car. I want to know what happens if I were to plead guilty, not guilty or no contest. I also want to be left with an option for expungement. I live in seminole county. any advice, referrals, or information will be largely appreciated.
