I’m right handed and wind my reel with my right hand. I think this came from learning to fish with my dad who was left handed and wound his reel with his left hand. I once tried changing to a left hand wind but found it really awkward so changed back.
I also read an article on the subject written I think by Lefty Kerf where the writer demonstrated the benefit of winding with your dominant hand, in my case right, by taking a piece of card and a pencil. If you hold the pencil in your dominant hand and the card in your other hand, as if you’re holding a reel, then draw a series of circles very quickly, like you’re winding a reel, the circles with the pencil or pen in the dominant are far more regular and concentric - try it!!
