Hi jay-9133,

Thanks for screenshots

1. Title: The section you are referring is Promo banner widget and you cannot place other widget inside it. You can use Title field to insert the title, but it also Fixed title only https://ibb.co/vzmbPvs

Or you can use WooCommerce Title widget > then you can add custom padding https://ibb.co/3C6bcCx and add background image as well https://ibb.co/KLSBYFt

2. Subcategories: Currently, categories widget supports these designs only https://ibb.co/2yppKqq For other designs, it requires complicated customization to make it works, which is out of our basic support.

3. Products: You can use Archive products widget https://ibb.co/G3H3YH9 to display products belong to the category you are viewing.

Regards,
