Which board should I be looking to buy next?

I currently ride an 8 foot soft top and am able to ride down the line in both directions no problem just from angling my takeoff. Im looking into purchasing a midlength to start learning how trim properly and generate speed.

I’m 5’9” and weigh 195 lbs. Also I’m surfing in Florida where the waves are generally pretty mushy. Does anyone have any recommendations for either specific boards, or at least some dimensions that I should be looking at buying?

Thanks guys!

(Also I completeded the beginner pathway, which was awesome, and have moved on to the intermediate pathway. Which is another reason why i think its time to graduate from my soft top.)
