In addition to the regular header you can also set hero title style for your main shop page and categories.
In the Customizer go to Shop → Shop Header and select one of the options in Shop Hero Title:
- Catalog pages only. Main shop and categories.
- All WooCommerce pages. Including cart, order tracking, wishlist, etc.
Choose the text color scheme and background color. This style will be inherited for all categories but you can change the style on each one.
Add Background Image
For the main shop use the Customizer option
For categories go to Products → Categories to upload your image and select the title color scheme
