That creeping yellow weed on the lawn is quite prolific where I live also. It's a type of clover although I don't remember the name.
Verdone lawn weed killer did the trick for me and it doesn't leave any black patches! It is grass friendly but I just targeted the weeds. Either that or you can comb it up from the lawn with your fingers till you find the root but it is quite stubborn to pull up!
My front lawn is quite clear now with minimal effort yet I have seen some who hardly have any grass left!
