Going to echo what Zach said about beginners and great lakes steelhead. If you could find a river where you wouldn’t have to contend with crowds…between the fish possibly humbling him, and crowds possibly leaving a sour taste….
If you can get info of a place thats a short trip Id try to find a Brook Trout Destination. They are aggressive, less concerned about presentation, etc, etc and really for most beginners they associate FFing with trout and at least up here, few species conjur the imagination than Brookies on the fly for beginners.
