Have a look at the demo code. The UserComboBox in the example and demo code is exactly the answer to your first question. You can set an [ItemLabelGenerator]
(https://vaadin.com/api/platform/12.0.7/com/vaadin/flow/component/ItemLabelGenerator.html) to control the shown labels. For your case it might be something like new MultiselectComboBox<>(user -> user.getName());

I don’t understand the second question. The setItems()-Method works with lists.

As of current date, what is the Vaadin-native way for multiselecting stuff? ListBox?

Vaadin still don’t have any (other than using Grid directly in multi-select mode).
However, I am using this add-on that is really good.
