It is hard to beat few CDN providers such as CacheFly, Akamai, Fastly, StackPath (MaxCDN) and so on. The choice is more limited if you want to narrow your option with origin pull CDNs.
The advantage of origin pull CDNs is that, their server will automatically pull the static files (including HTML) on their server. You have nothing to configure on WordPress except adding the root URL of the CDN. The disadvantage is that the price to maintain the reverse proxy makes the total cost higher.

In the past 13 years, we have seen both Akamai and CacheFly perform at similar speeds. However, the normally available CDN service of Akamai usually origin push. Among the origin pull, the options are CacheFly, StackPath and Fastly.

If you want to just offload the static files towards a hassle-free, high-performing CDN, then CacheFly is the best choice. On a pay-as-you-go unmanaged account, your total payable bill will not be something like $10 per month. CacheFly, StackPath and Fastly practically have no competitors when it is about performance. But their cost is higher than many others. If you need reliable performance, then you can test all of them.
CacheFly, Fastly, StackPath all supports HTTP/2 and Brotli. Support of HTTP/3 usually available with higher plans of any CDN service.
