Rendering vocabulary titles in templates for objects instead of value

I have objects for where a field stores SimpleVocabulary term, using DefaultView and view/w this will show the correct values for templates on the current object itself.

What's the proper way to get titles instead of values for nested object fields for nested objects using listFolderContents? The following would return values eg. "en", instead of the title, "English"

<span tal:repeat="item context/listFolderContents">
    <span tal:content="item/vocabvaluefield"></span>
</span>

...best to wrap the related code into a browser view method.
