Welcome in the family. Former skier...rider since 99, seriously the last 3 seasons.
One suggestion, buy relatively cheap board, good bindings, comfy boots, helmet ass pad and wrist guards.
You won't notice or appreciate the difference with a high end board while learning, but you will appreciate it when you get better, so kep that for later, also you don't have to wory about damaging it or having it stolen. I got a Ride Control for 200 bucks 5 years ago.
Good bindings that you can swap with a new board eventually, and comfy boots to ride better. Be sure that they (at the shop) match your boots size to the bindings. I realized years later they gave me a LARGE binding for my 9.5 boot.
Helmet use is obvious, and the protections will keep you riding another day as you fall as we all did.
Wax your board, and enjoy!
