Kleo elements – VC elements in posts – SEO – Post templates

I’d like to use the blog structure with posts for SEO reasons. At the same time I’d like to integrate an VC-element into a post.
Cannot find neither post templates with full width nor VC-elements for posts.

What I’d like to realize:
– it could be a full with post template
– or a post template with a full width area after or before the post content
– or a page with a post area

The last option perhaps doesn’t make any sense because if I would use tags in the post area of the page it would probably link to another post and I would have no full width area any more.

Am I missing something?
I’m sure you have a better overview with kleo than me.
How would I do it?
