Using Cloudflare with W3 Total Cache on woocommerce website

I am using Cloudflare together with W3 total cache on my website and followed this tutorial to set it up https://www.mprstudio.com/speed-up-wordpress-w3-total-cache-cloudflare/ . Please let me know if this is correct to do incase of a woocommerce website or are there any other settings that i should do. What will be the benefit of enabling AMP on cloudflare and should i really do that? Thank You
