Liston is probably able to outjab him, he has better balance and fundamentals and would likely punish him with the jab. He needs to bring the fight to his pace and pummel him with the jab and let the opportunities come themselves.
Wardley was born in 1994 so he can't be better than Itauma who was born in 2000 On a serious note, I'm just not impressed with Listons quality of opposition. Id probably favor Beterbiev over everyone Liston beat H2H. His best win is probably Patterson who lost to ingenar Johansson or alternatively Williams. You don't think Wardley could beat everyone Liston beat?
