For now, I am able to get the ListView to redraw and correctly indicate the selected default by using the following method, called forceListRefreshOn(), in my button handler:

@FXML
void handleAliasDefault(ActionEvent event) {

    int sel = lsvAlias.getSelectionModel().getSelectedIndex();
    if (sel >= 0 && sel < lsvAlias.getItems().size()) {
        lsvAlias.setUserData(lsvAlias.getItems().get(sel));
        this.forceListRefreshOn(lsvAlias);
    }
}

The helper method just swaps out the ObservableList from the ListView and then swaps it back in, presumably forcing the ListView to update its ListCells:

private  void forceListRefreshOn(ListView lsv) {
    ObservableList items = lsv.getItems();
    lsv.setItems(null);
    lsv.setItems(items);
}
