I am thinking about switching to cupric chloride as in theory I should not have much of a waste product.
That's right. If you get too much volume increase of your solution by using it, some can be neutralized and it precipitates copper oxide out. The remaining water is low copper and neutral, so it can go on the yard plants.
Yes, store the solution outdoors and use outdoors away from your favorite cars, tools, or anything else since it releases chlorine and HCl mist from bubbler operation.
