I think you need to think about what you don't want.
Drool? If that's a no, it rules out most family-friendly first time breeds (St Bernards, Bernese, Goldies, Labs, Boxers).
Don't want to be covered in fur? That rules out Goldies, Bernese, Labs, Collies (or most shepherds), Corgies, Samoyed etc).
Don't want one too intelligent (i.e. lots of training really needed)? That rules out Collies, most retriever breeds, poodles, most spaniels etc.
I'd go for something like a Bichon Frise. Pretty healthy, good with kids, reasonably good with other dogs (training permitting), robust, no drool. Needs grooming a lot - but tbh there's no such thing as 'the perfect dog.'
Hardly any dog owner loves absolutely everything about their dog - it's about finding a dog that ticks 'most' of your boxes and learning to love the bits you really hate. Personally, I absolutely hate fur. I hate hoovering. But, I have a Goldie - because he is perfect in every other way and so I look past his bloody fur.
