Finding the right theme to showcase fitness coaching

Hello, everyone!

I'm looking for a new wordpress theme that expects to cover the following key sections:

• About Us
• contact page
• Blog Posts
• Demonstration of changes in fitness body image of previous clients (including before and after pictures and client testimonials)
• Pages for products I personally use
• My page on the online tutoring services I offer

I don't need overly complex features, but want the theme to look nice, be responsive, and easily support multi-language translation.

Any recommendations for themes or templates, or experiences shared in setting up these pages, appreciated!
