Advice for potentially getting a sheepadoodle

Never owned dogs. My husband is desperate for one and wants a sheepadoodle. Any advice on temperament and ownership of these dogs ? Our kids are teenagers , usually someone home for most of the day . Probably couldn’t walk more than an hour a day . Have a garden and no other pets. Want to avoid highly strung dogs , dogs that bark a lot and dogs that chew everything in sight - any thoughts ?
