Finger noise drove me nuts.
A certain amount is inevitable with round wound strings, especially steels. As previously mentioned it largely gets lost in the mix of a full band setting but I hated it when playing on my own.
I switched to flat wounds, Ernie Ball Cobalts to be precise which still retain a certain amount of the round wound sound with reduced noise. D'Addario Chromes are another option for flats that still retain a brightness.
Coated round wounds may be another option. I think Elixr do them, Nano web coating I think it's called?? Worth investigating too.
Other than that, practice practice practice.
