Whippets are lovely dogs, shedding is not too dramatic and they are generally easy going. The only concern would be that they can be a little nervy around too much noise?
A poodle would be a great choice for what you are looking for, thrive on being busy, but with the right training and exercise level an excellent family pet. They don-t shed or have that 'doggy' smell and although they need regular grooming, the pet clip is really easy to keep on top of yourself or a quick trip to the groomers.
It sounds like you have a great set-up and the time to bring on a young dog, but it is always worth taking a look at local rescue centres. If you can find a reputable one that puts effort in to properly checking a dogs temperament and family suitability. There are many a young dog, out of the puppy stage and just in need of proper circumstances to thrive. All breeds have pros and cons, sometimes a crossbreed gives the best of all worlds, sometimes not so much.
If you are set on a pedigree puppy then carefully research both parents and the breeder. Be wary of in-experienced designer cross-breed breeders. They have often not had the animals checked for the usual breed issues like hip and eyes, skin conditions etc.. you won't find out if a poodle criss is going to shed until they are 1-2years old and there is no way to guarantee the coat type whatever the breeder claims. My friend as a gorgeous labradoodle, mad as a hatter, high energy, high intelligence and all round bundle of fabulousness, but he sheds like you would not believe, think a cushion full every month!
Both the Vizla and Weimaraner are not ideal first dogs, they are a working breed and generally need to be with their people ALL the time and a job to do to prevent behavioural issues. From my experience of both breeds they usually tend to gravitate to one handler rather than a group, not in an unfriendly way, just a stronger bond.
Have you considered a dalmation? They usually make great family additions and love to go running. Again quite high energy, but normally fairly quiet indoors.
Labs are brilliant dogs, grew up with them, but usually strong willed and likely to pull small people over/mow them down in excitement. They are very destructive as puppies and the show lines are pretty stubborn to train. Shed heavily twice a year, stay wet forever (double coat) and have a magnetic attraction to muddy bogs and any form of water. They are loving, great fun and generally very friendly though!
Sorry for the waffle, my recommendation would be a poodle I think, I know not on your list, but really would fit in with your lifestyle very well.
