The service is really well-suited for pretty much any site that is primarily display-driven (that is, mostly GET requests). The network is able to handle massive volumes of traffic and their POPs have spread out pretty much anywhere that it's easy to get them (so basically everywhere but China and Russia). My team witnessed several large-scale attack attempts on some high-profile websites (attacks in the 10s of millions of requests per second) that were mitigated before ever coming back to the actual application; in one case we didn't realize the attack had happened until we looked at the logs the next day. Because it's a cache store option, the default configuration does not cache POST responses, and it can be difficult to set up things like authenticated paywalls as a result.
