What to study particularly if we are to purchase the services of Cloudflare? Main products to get are CDN, China Network, DDOS.

We will be having a meeting with bosses that we are to purchase the services of CloudFlare. They want CDN, China Network, DDOS protection. Kind'a want to be prepared before the meeting. I understand that I need to study those Key Products. But where do I start? I do have CCNP level networking background. Where particularly in Security I need to study? Hoping someone with experience with Cloudflare chime in. Very much appreciated Sirs!
