Hello, @TFS,
Here are the designs of the testimonial element in our theme: https://xstore.8theme.com/elementor/demos/minimal-fashion02/testimonials-element/ you can use the element and set it as per your requirements on any of the site pages.
And unfortunately, there are no other elements for rating/reviews to show on the site page, you have to try with any third-party plugin which better meets your requirements.
Regards 8Themes Team.
