I suspect spectacular routes with decent huts will be busy. August is euro holiday time and busy. So expect to experience some busyness!
Countering that though....
Avoid places within easy access of mechanised lifts and motorways at weekends and you'll probably be OK. Last week of august / 1st week September has been OK in my experience, but I guess that depends on term start dates. Many huts have small family rooms, so if you book ahead (often only a day is enough in the Dolomites) then you'll get one and avoid the main busy hut problem of poor sleep in a big dorm.
3000m summits may well be subject to snow at any time of year - not enjoyable with family if you get caught. Same goes for glaciers/old snow patches unless you have 6 point crampons or better.
Do you want summits? (I expect your kids will!) If so then I'd aim for stuff in the 2-3000m range as you'll be above the treeline and get the views without the issues higher altitudes have.
Do you want Via Ferrata?
I can't advise on 5-7 day treks as I've not done any. See if you can get hold of 'Walking in the alps' by Kev Reynolds as that gives some suggestions and is a good overview. I want to do the Lechtaler Hohenweg, but I don't know how suitable for your needs that is.
