I like a lot of your favorites, but if I had to pick the ones I like best, I think I'd choose...
Boys
Charlie - very likeable
Jack - the #1 boy name in the UK right now
Kyle - a great choice, esp. if you happen to be Scottish
Leo - simple & strong, with a lot of history
Mason - one of the best occupation names out there
Girls
Daisy - such a happy name
Heidi - always had a soft spot for this one
Matilda - mature-sounding, with great nn possibilities
Ruby - old-fashioned sounding, yet still evokes a cool image
Simone - short, sweet & pretty
