I've only tested this on the Yuga theme per a user's report.
They want to apply their custom FSE template to their "Product" page, which is also their designated WooCommerce shop page. When this shop designation is applied, the custom FSE template gets ignored. With the Woo shop page designation off, the custom template appears as expected.
They're wanting both the Woo shop designation for their page as well as the custom template to appear. I am able to replicate this on my test site.
Steps to reproduce
Create a custom FSE template
Apply this template to a page that displays WooCommerce products
In WooCommerce > Settings > Products, make sure you have a designated shop page.
View the page and you'll notice your custom template isn't applied.
In WooCommerce > Settings > Products, remove the page as the designated shop page(leave the shop page drop down blank) and save your changes.
View the page and you'll see your custom template now appears as expected.
What you expected to happen
For the custom FSE template to appear even with the page assigned at the WooCommerce shop page.
What actually happened
The custom FSE template doesn't appear as long as the Woo shop page designation is assigned to the page.
