Airedales are terriers and if you think about the work of a terrier, much of it is the dog alone doing the work - albeit with a handler. This means they can be stubborn and independent. They are also clever and require mental stimulation to stay happy. Think something akin to a couple of hours good walking (countryside with lots of smells or similar) and another hour or so of one-to-one training and interaction. He will require a bit more than that on the days you leave him alone, otherwise you risk his boredom turning to destruction while you are out.
Sproodles are springer/poodle mixes. The issue with a mix is that you cannot be sure whether you will get the best of both breeds or the worst. You need to be prepared for the worst:
Springers are another high energy breed that requires similar walking and interaction to the airedale (minimum). They are also bred to work alongside humans and so are more prone to distress when left alone. That distress could turn to destruction. They are also gun dogs so mouthy, especially when young. Your children will require preparing for a chewy/mouthy dog with needles sharp teeth.
Poodles are similar to springers, but smarter and often more sensitive. They need a good amount of exercise and hate being left alone, generally. They also need an especially kind hand (all dogs do, but you know what I mean).
6-10 hours is far too long to leave any dog unattended (maybe six hours, at a push for a very old and docile dog who just settles down to sleep). For all other dogs, four hours, max, before someone comes in to toilet and walk him. A 10 hour day means someone in twice or day care for the full day.
My dog is a show springer - they are a bit calmer than working springers - and still needs something akin to 3 hours a day one-to-one time (walking, training, playing). And he is just a puppy who cannot walk too far right now. Once adult, he will need 4 hours plus.
Honestly, while I understand thinking some dogs are cuter than others, pick for temperament and not for looks. Once you get a dog and love it, the looks not longer matter - they ALL end up looking beautiful. I also have a little rat terrier with no teeth and funny eyes. When we got him, at one year old, I thought he was an odd looking thing. I now think he is the cutest dog ever.
All dogs are active so even the 'lazier' ones so don't worry about not being able to do activities with them. Assuming you can do something to prevent the 6 hours alone, a companion breed is a good starter (Cav King Charles, for e.g. though these needs to come from a top notch, excellent breeder to try to avoid the awful health issues).
Alternatively work with a good rescue centre and get an older dog of any breed with the right personality for you. All breeds have typical and non-typical members so you can find lazy springer, for example.
