Thoughts on your list:
Girls
[name]Phoebe[/name] a sweet, sunny, happy name that works well on a young girl as well as an adult. Classical associations, a long history, not too common but still familiar. However-- it’s quite a bit different in style from [name]Shea[/name] and [name]Scout[/name], which are hip modern inventions.
[name]Zooey[/name] back when [name]Zooey[/name] Deschanel was born, nobody was named [name]Zoe[/name], so her parents spelled it out. Luckily you don’t have to anymore, and can go with the much more elegant and trim [name]Zoe[/name]. This too is sprightly like [name]Phoebe[/name], but it’s much more common. I do think it’s a bit closer to [name]Scout[/name], principally due to the zippy Z and the shorter length.
[name]Stella[/name] this is on-theme as an S name, so it might work. [name]Stella[/name] is an antique which has been revived on the heels of [name]Ella[/name] and [name]Bella[/name]. It’s sweet with a nice astronomical meaning (what little girl wouldn’t want to be thought of as a star?)
[name]Winter[/name] ([name]Winnie[/name]) [name]Winter[/name] is a modern name in the vein of your children’s names. I personally think it lacks substance, as do the other calendar names ([name]June[/name], [name]May[/name], [name]Summer[/name]). [name]Winnie[/name] is an adorable nickname but there are other ways of arriving at it ([name]Winsome[/name], [name]Wynne[/name], [name]Windham[/name]).
Boys
[name]Cash[/name] rocker-cool in the vein of [name]Johnny[/name] [name]Cash[/name], but of course a very common everyday word. [name]Don[/name]‘t know too if you want to name your son something so reminiscent of money.
[name]Finn[/name] this fits well with [name]Shea[/name]-- a sleek Irish boys’ name, also a common surname, which is unpretentious. This is a real winner.
[name]Sullivan[/name] on-theme with the S, but significantly longer than the monosyllabic [name]Scout[/name] and [name]Shea[/name]. Unless it’s a family name, I’d look elsewhere.
[name]Boone[/name] [name]Boone[/name] is a cool redneck, like Led [name]Zeppelin[/name] or [name]Woody[/name] Harrelson. It fits well with your children though will definitely carry a backwoods vibe.

Re:[name]Jameson[/name]: I assume your dad was named [name]James[/name]? It’s very sweet to honor a child of either gender after him, but for a daughter I wouldn’t necessarily put “son of [name]James[/name]” in the middle spot (a bit reminiscent of [name]Jenna[/name] [name]Jameson[/name], too). For a girl you could consider:
[name]Jamie[/name]
[name]Jamila[/name] (common Arabic name meaning "pretty)
[name]Janis[/name] (like [name]Joplin[/name])
[name]Jadis[/name] (fictional queen in [name]Narnia[/name])
[name]Janelle[/name]
[name]Jasmina[/name]
