If you’re in the market for a nice switch case but can’t afford the skull and co case, check out this. JETech case for the switch. $12 on ebay and amazing quality.
It's all about that Skull & Co. best dockable case and most ergonomically designed for my big ass hands. It comes with its own carry case too! It's unbeatable.
I don't think there is a case that support the official dock... The gap between the console and the dock is so small that any case will just be making the Switch to big to fit in the dock.. I was looking into this quite thoroughly and unless you find very specific cases or use custom dock specs than I don't think that you're gonna find any case that works with the dock
