ETH Staking APR 10%?? Please help a smooth brain

Can somebody kindly explain to me the difference between execution layer rewards (with examples) and consensus layer rewards (with examples)

I also don't quite understand "MEV". I'm trying to understand how Lido and Rocket Pool (the top two liquid staking protocols) can offer dynamic APRS in excess of 10% sustainably… I understand it's as a result of the combination of CL and EL rewards but that's about it.

Thank you kindly in advance.
