If Hitlers vision was a Jew free Europe. Did he have anything he wanted to do after he accomplished his goal?

Turn large swathes of Eastern Europe into Slav-free areas in which German farmer-soldiers would live in little totalitarian communes dedicated to Nazi ideology. There was a strong agrarian element in Nazi ideology to the better-known militarism.

He didn't just want to genocide the Jews. He had a damn long list. Gipsies, disabled people, homosexuals, etc.. It's virtually quicker to name groups he didn't want to wipe out.
