I was in the same position as you a couple of years ago. I eventually went with poodle. Mostly because I’ve known a couple of schnauzers that were quite yappy and one of my children is sensitive to noise.
My mini poodle is now almost 1 and a half. I know all dogs are different but I will tell you how ours has been.
He slept all night, no mess from the first night! I was amazed! Possibly partly because we didn’t collect him until he was 10 weeks and most of his siblings had already gone.
He took a couple of months to be completely toilet trained. The bells on the door handle helped massively. He still rings them now to be let out into the garden.
He was never very nippy and hasn’t chewed anything really. Not destructive in any way. He does like to eat. And as a puppy we couldn’t leave anything on the floor without him picking it up. Now we can leave toys out etc but I would always put them away if we were leaving him on his own just in case. It doesn’t have to be food for it to look tasty 
We didn’t do puppy classes but had a couple of 1-1 sessions with a trainer in our house which were great. He is great with ‘drop it’ and ‘leave’ and ‘spin round’ (less useful) and things like that. I’m having a 1-1 session again as we haven’t been consistent with lead walking and he can still pull.
His recall is about 80%. He is a people dog and would happily great anyone by jumping up to say hello so we have been working on that.
With my kids he is great. Loves to be involved with any game they’re playing in the garden. Also happy to lie down next to them when they sit down for a while.
He does like his gang (us) to be together and when I leave him with my parents he mopes about a bit rather than playing like he does when we are home. He is fine being left for a 2-3 hours but not needed to leave him for longer anyway.
He does have quite a high prey drive. And a squirrel will always get his full attention. As do the pigeons in our garden. He’s never caught anything though. He once brought me a baby bird but he was just carrying it and dropped it when I said. It was perfectly fine! Don’t think he really knew what to do with it to be honest!
While he’s happy to have a deep paddle in mud or water, he doesn’t much like the rain and doesn’t enjoy swimming. Though poodles were bred for retrieval in water!
I spend about £35 every 5 weeks ish. He’s just pretty short all over. Not shaved.
