Should I switch my ETH 1.0 to ETH 2.0 on Coinbase? Where is the best place to pool ETH?

Do I need to switch my 1.0 ETH to 2.0, like is there any advantage to having one over the other?

I have 10 ETH and would like to pool it to stake it. Hopefully one day I can get to 32 ETH. Where is the best place to do this?
