You can go to the Customizer → WooCommerce → Product Catalog to set the initial sort order of products in your online store using the WordPress Customizer. You can choose default sorting (custom ordering + name), popularity, average rating, most recent, and price.

To enable the default WooCommerce product sorting, go to your WooCommerce → Settings → Product Tab. In the drop-down menu, you can see the default product sorting that focuses on different classifications, such as price and popularity.
