The choices are floral and floral fresh I want eau fraiche I'm not sure which one to get

I’m not sure in what context or place those choices were presented to you. Chanel makes 2 fragrances in this line. Eau Fraiche (green), and Eau Tendre (pink). If it’s Eau Fraiche that you want, go to some other site that is less confusing.

Hello 👋 what is the difference between floral and floral fresh ?

Where are you seeing those distinctions? On what site? Chanel makes 2 eau de colognes in the Chance line - one is green in the bottle and is called “eau fraiche”, the other is pink and called “eau tendre”. Go into a department store and test them out!
