New Surfer Question

Hey! Looking for a little help! Surfed last week in Jaco. Lessons were great and picked it up fast on a big foam board. Got to the bigger waves by end of first day and was able to stand up. Spent the next two days surfing on my own. I rented a 7’6” with one fin. I kept it simple and caught a ton of waves in the whitewash. Felt comfortable consistently getting up. When I paddled out I had a hard time. Definitely from from my inability to read waves, but I’ll get there.
I am looking to buy a first board. I’m in south Florida. I’m 5’6” 145, 50 yo and active and athletic. Any board recommendations? 7’6” felt like a lot but not sure? Was looking at Walden Mega Mega Magic. I know having volume is major for me being able to develop. So maybe a 7’-7’2” but more volume? Appreciate any guidance.
