Was it definitely a crossbreed?
Something called an Esky which is a crossbreed sounds like it would probably have Husky in it. I wouldn't recommend a Husky for your needs as they are such high energy dogs and really need knowledgeable homes with experienceo of the breed.
I am completely biased, but my Soft Coated Wheaten Terrier would have been perfect. She was very intelligent, really friendly and I can honestly say one of the easiest dogs I've ever lived with. She was also the easiest dog I've ever trained and absolutely adored children. We did obedience, agility and heelwork to music together and she loved nothing better than a good training session. I have three dcs myself and my oldest ds has ASD - she was always really good with the children, even when they were tiny.
My ds has never been interested in our dogs, which is a shame, because he suffers from extremely high anxiety and I think developing a good relationship with a dog could help him in many ways.
Other than that, if you would consider a rescue I would recommend going to a reputable rescue centre and asking their advice and whether or not they have any dogs/pups that might be suitable. There are such a lot of amazing dogs stuck in rescues that would make wonderful family pets and would be so keen to learn and be trained. The danger is in falling in love with one that's completely unsuitable, rather than taking the advice of the rescuers who will have spent time with the dogs and got to know their temperaments and strengths and weaknesses etc.
If you don't want to go the rescue route and aren't rushing into anything, a trip to Crufts to visit Discover Dogs would be a great way of getting to see lots of different breeds and talk to breeders and owners. I'd advise taking a shortlist of preferred breeds with you though, as there are a lot of dogs to see and its easy to be sidetracked.
