If you want eggs of different colors Welsummer (chocolate brown eggs) are friendly, Americanas/EE (green, blue egga) mine follow me around & will tolerate me picking them up! Barred Holland (white eggs)
I don't know about most of the birds you listed, I don't like my wyandottes too much. Too Skiddish.
But buff orpingtons, Barred rocks, and speckled sussexes are supposed to all be very sweet birds. I'm adding them this year. My sexlinks are kinda mean, always picking on the others.
Dark egg layers are just a cool addition to the laying flock I would get sexlinks, marans/barnvelders/welsummers, and EE's that would be alot of veriety in your egg basket.
