Non-Custodial Staking with Ethereum

Since I have some Ethers sitting on my bag and I'm not looking to sell it in the next years, some people pointed out it would be a good idea to stake it.

I don't have the technical abilities to run a node for myself so I'm looking for a Non-Custodial Staking. I found two companies (Staked and Stake Fish) that look like a reliable place to put my ethers, but at the same time I didn't find too many people using them.

As it is always weird to send my ethers to other people and because of the fear of validators slashing, I'm being hesitant to put my money there.

Does anybody have some good feedback about those two companies or any other Non-Custodial Staking companies?

I'm also looking to put the residual ether (above 32) on Lido. Any advice for a rookie staker using the platform?
