The custom product layout which is accessible through the customer experience layouts is a great way to easily design your own product pages. Here you can add further pictures and texts to enhance your product listings and make them more vivid.

The general layout where to place pictures and further texts can be created in the customer experience layout section.
The individual pictures and texts per product are then choosen and created under calalogue -> products -> layout (tab).

In this way the following example of an indivudual product listing is possible.

However: The custom layout is only editable on the product level - not on the product variants level.
If I sell red shirts und blue shirts I would like to enhance my product page of the red shirt with fotos and texts suitable only for the red one, which is currently not possible.
