How important is WHERE I stake ETH for ETH 2.0?

I've made a decent amount of magic money off of Dogecoin and wanted to take some of those profits and stake them in Ethereum. I was about to do it on Kraken because that's where I have my Doge but they have some kind of message for people living in the US saying I wont be able to trade on the Ethereum 2 network or something? I don't know enough about Crypto to understand what that message means so I decided to move the Ethereum to Coinbase and stake it there but now I'm on a waitlist or something?

So I guess simply put, where is a good place to stake ethereum and how much does it matter? Thanks, excited to be on board.
