Regarding the blog function.

Regarding the blog function, is it possible to retrieve only articles that have been multilingualized?

for example.

{% if languages_count > 1 %}
 {% ... %}
{% endif %}

This will work. It depends if you want to return the primary language version of the blogs that have mutli-language variations, or return the multi-language variations themselves.

{# return primary language version of blogs which have translations #}
{% for content in contents %}
 {% if content.translated_content|length %}
 {{content.name}}
 {% endif %}
{% endfor %}

{# return translations of blogs that have them #}
{% for content in contents %}
 {% if content.translated_content|length %}
 {% for item in content.translated_content %}
 {{item.name}}
 {% endfor %}
 {% endif %}
{% endfor %}

I would also recommend adding a check for published, which would be

{% if content_by_id(item.id).current_state == 'PUBLISHED' %}

{% endif %}
