Buying a new board tomorrow

Buying my first board tomorrow. I'm stuck on what to get. New to surfing but I'll be doing it often bc I love the water and any water sport in general so I don't want to just buy a longboard and then want something with more maneuverability than a LB or funboard a month later. I'll be surfing in south Texas so smaller waves will also be a factor. Any help would be appreciated! Thanks!!! Forgot to mention, I'm 5'10 175lbs and in good shape.
