Labrador retriever.
Most labrador dogs have a good disposition and they are very hyper.
A labrador may run after children just because it wants to play also children are alot more active than adults which gets any dog excited.

A good breed of dog to own if you're allergic, is a cat.
Mating a St. Bernard with a Labrador might create a good breed of dog. Both the Labrador and the St. Bernard are friendly and loyal.

If you are getting a labrador while it is still a puppy, then yes the dog will usually get along with the cat since they will have grown up together. and it also depends if the cat is used to dogs, if not the cat may run from the dog or attack when the dog is near it and they will not get along. My labrador gets along fine with cats, it the cats that don't particularly like my labrador.
No, Labrador Retrievers are one most the worst breeds to be a watchdog! They will bark, but that is more of a friendly invitation instead of a warning.
I see that you are asking about many dogs. Unfortunately, I don't know much about those breeds, but I do know that beagles and Labrador retrievers are excellent first dog. My first dog was a Labrador retriever and he was my favorite dog.
