You've got some very specific requirements there!
I don't recommend Sussex. I've had loads and they are broody broody broody!
I do recommend Welsummer, English Marans, Wyandotte and Barnevelder. I have nothing bad to say about any of these breeds, having kept them all myself.
They are savvy enough to avoid predators but not too flighty, lay a decent number of eggs but not so many to wear out their insides in 2 years, and are inquisitive, confident, excellent foragers, entertaining characters (and vocal). Clean footed, non crested. They come in gorgeous colours and are fairly hardy in all weathers.
Orpingtons are pretty, but not food/egg efficient at all. Too many feathers taking the protein.
Polish are a no no with hawks around and free ranging over a large area. They just have no peripheral vision.
I'd recommend Naked Necks as they are brilliant birds but their appearance may give you the ick.
Most chicken's friendliness is down to how they are raised, not their breed as such.
The best tempered cockerel I've had is an Araucana. But they lay blue/green eggs and you want brown.
