Tag pages with regular editor

So, I am creating a website, review products and attach dozens of tags to them dependent on what the product entails.

I have a custom review template for my products and based on what I tag the products as they will automatically show under the given tag-page.

Now, my plan is to use the tag-pages to create content and rank with it.

The problem is that the tag-editor is pretty limited in regards to its functionality, so I do not have much freedom in regards to design.

I would like to have some of the options I have with the editor for regular pages and posts, available for the editor that's set default for tag-pages.

For example, I would like to create blocks/sections for my tag-pages and give it a featured image.

Basically, I want to treat the archive pages as regular pages with the help of an editor that allows several functionalities.

Thanks for any help.

Best regards, Pierre
