WP Rocket is generally a good caching solution for WordPress websites.
However, FastPixel takes this to another level. It not only caches the HTML but also includes built-in CDN support with adaptive image optimization and WebP conversion.
You can read more about how FastPixel handles images here:

Additionally, all the HTML of each optimized page, along with CSS, JS, and fonts, is processed in our cloud. These assets, including Critical CSS, are then delivered via our global CDN for maximum performance.
You can quickly run a test without installing the plugin here:
