Can You Give Me Info On These Breeds? Pom, Papillon, Havanese, And Cavelier King Charles Spaniel?

Do they need a lot of grooming and a fenced yard? Are they intelligent and playful? Do they shed a lot? Thanks!!

Havanese Or King Charles Cavalier?

I’ve narrowed down my puppy search to these two breeds. I love the temperment and look of both breeds but have no actual experience with either.
I’m a stay at home Mom and so I have lots of time to devote to care and training of a puppy. We have a large lab, three kids and two indoor cats and so I was wondering if anyone had an opinion on which would be the better choice for my family.
Thanks
