Mini 3 Pro is a great drone but I wouldn't trust it in strong winds, as Flex said the FPV would be better or one of the bigger drones for strong winds. I have a Air 2s which is great but I bought it mainly for travel not chasing windsurfers, I do occasionally chase windsurfers but really I have too much to lose just to film others.
Yes the mini 3 is a great drone to start with and probally all you'd ever need, the integrated screen makes life easy. Factor in extra batteries and if you go the Mini 3 and get the larger ones.
