HiCavitation andRanger1. There are sooo many options it can be a bit confusing at times so I thought I'd help you understand some of the terms used for boards and sails. Most brands have similar variants.
On a spectrum that goes manoeuvrability to speed:
Wave, freestyle wave, freeride, freerace, slalom
I have not included Freestyle - this is something newish you might not be familiar with and is all about tricks - lots of board and sail rotations.
Freeride is a good place to start looking, it's designed to be easy and can do a bit of everything. Then go to the left or right depending on your preference for waves or speed. It's quite common to have gear that may sound very big compared to 15 or 20 years ago - an 80kg sailor with one freeride board would probably look at around 120-130 litres and about 70cm width using sails from 5.5m to 7.5m.
Here are some examples of freeride boards that you'll find in Aus

and some sails

You can still get boards with centreboards although these are usually for three purposes -
racing around a course that involves upwind legs
learning boards to stop beginners drifting downwind
all rounder boards for a bit of exploring and a very broad wind range
Hope that helps
