{% for i, value in content.field_category %}
  {% if node.field_category[i].entity %}
    {%
      set cat = {
        url : path('entity.taxonomy_term.canonical', {'taxonomy_term': node.field_category[i].entity.id}),
        title : node.field_category[i].entity.name.value,
      }
    %}
    <a href="{{ cat.url }}">{{ cat.title }}</a>
  {% endif %}
{% endfor %}

Thanks! This also works for any generic nodes, including teaser view modes as long as you are rendering the node.
