Here is a tutorial for adding custom fields to a WooCommerce product and displaying them on the products template:
https://themeisle.com/blog/custom-fields-woocommerce/
Another option for displaying the values from your ACF fields on the products template outside of using the short codes which the above tutorial does not get into is WooCommerce provides a number of hooks/filters that can be used with the single products template to add information/customize the output. These hooks/filters can be placed in the functions file of your theme to output the additional ACF fields you want to include on the products template.
Hope this is helpful!
