To be honest, that's the ONLY part of the planning that is not going well. I want a dual purpose breed for meat and eggs that doesn't go insanely broody, has a good temperament, and will be healthy and sturdy. I'm thinking about Black Australorps. And Ameraucanas. And Dorkings. And Brabanters. And Speckled Sussex. See? I want ALL THE CHICKENS!
If you want to get birds from a hatchery, it's easy to solve: buy about 3 hens and 2 cockerels of each breed, raise them all as one flock, and see which you like best. When any bird becomes a problem, eat it. After the first year, order more of the one kind you liked best and eat all the rest. After that you'll be all set to hatch your own.
If you want to buy from breeders, then maybe you could start by looking at what is available in your area. If someone is raising them locally, then their birds are likely to do well in your climate, and seeing the birds in person could help you learn whether you like the breed. It is also much more convenient to drive a short distance and pick up the birds or eggs you are buying, instead of planning a long road trip or arranging for them to be mailed
All of the breeds you named sound like good ones for your purpose!
