Your weight and height clearly recommend around 9ft, a normal board willm be a little harder to paddle at first from the foamy. A bit more skittish, but that is its manouverability . Get a 2+1 fin set up as that will allow you to play around and discover the joys of different fins.
Your catch rate will drop a bit at first and little less forgiveness from the foamy but lots of surfing ( recommended9 will bring you up to speed1
good learning journey ahead for you
