Based on the way the question is written you want a single page website with that one page displaying all products within a single category.
Install and configure WordPress and WooCommerce create the desired product category and add all relevant products.
Do not create any menus.
Then…
- Go to Appearance -> Customize -> Frontpage -> Product Categories
- Customization option of WooCommerce Category section are divided into 3 parts
Product Categories:
Product Category Layout:
Product Category Color & Image: - Insert the section content & select the category layout
- Click on “Save & Publish” to save your changes.
Hope this helps.
Best.
