The template is of multiple types for WordPress as the template is basically a piece of code or design including HTML/PHP/js code. There can be

1. Code Templated - A theme template file for the posting page, archive page, etc with UI only

2. Design Template - Page builder template like for Elementor

The template can be code only when we work with child themes for customizing default archive pages of a theme. While working with page builders, it can be a design page template with widgets, text, or images.

Template is basically a layout to organize your content so that it becomes easier for the users to navigate your site

A design template or template is a file that is created with an overall layout to be used with one or more documents. For example, a program might have a template for a resume. With resume templates, the overall layout is designed with placeholder text (e.g., your objective, previous job experience, etc.), which you can replace with relevant information for you.
