You can either use Post categories, or a cleaner option is to create a Custom Post Type (aka CPT) for each type. This can be done easily with ACF ([https://wordpress.org/plugins/advanced-custom-fields/](https://wordpress.org/plugins/advanced-custom-fields/))
So you might setup a CPT for “Case Studies” and “Articles”. Leave Blogs as “Posts”.
