Anyway, yes you can earn in liquidity pools and staking but it isn't big or it depends on some factors.
Being a liquidity provider has some risk because there is a chance that one or both of the coins that you put into the pool might lose their value thus, the amount of tokens you are getting being a liquidity provider isn't enough to cover your losses. I've been a liquidity provider in Katana (Axie Infinity) for more than half a year already and TBH, the amount of tokens that I got isn't enough to cover the losses that I got when I started. It might happen to you as well if you will not make an in-depth research. Now with regards to the percentages, I can't give any particular website but maybe some can give you here or you can just make a quick google search in the most popular liquidity pools out there and you will find one.
Now with regards to staking, yes you can earn money on that as well but it isn't that much. Some staking coins give as low as 1% to as high as 15% or even higher annually depending on the coin you chose to stake. What can I say is that if you want to stake, choose those top staking coins. Less risky but lesser reward as well. It's your choice still. You can find some staking coins here: https://www.stakingrewards.com/
