Custom post types

Hey WP helpers,

my boss gave me a premium WP theme that’s pretty advance, (I will post theme’s webpage if needed), I was wondering what the best approach would be to output a post with specific items in the content (the schema/items this post would include are Name, Website, Description, Image, Categories [<<< note Categories] )…

So should I make a specific category for these types of post to output on a certain page but then within this post category and then just use tags instead as the Categories part of the post schema.

In the back-end this type of post will need those specific schema items as fields on the edit post page.

TLDR: looking for a best approach to output a post with specific schema items that are easy to input from the admin dashboard, the issue is complicated by trying to accomplish this with minimal edits to theme (which may rule out solutions involving advance custom fields plug-in).
