What's the best way to Stake 32 ETH?

Hi guys, from this insane dip i've sold some stock assets and bought ETH which I plan to hold for at least 3 years without touching it, I know we can stake it and earn passive interests which interests me currently.

Problem is, i've digged to make a node and it seems like there's an unstake delay, isn't there a way to stake it without delay during unstaking? Thanks
