If you use argo caching on Cloudflare, it should reduce origin server load even more. Essentially, instead of going directly to your origin, cloudflare endpoint will first reach to it's root node to see if it's cached there and only that node is allowed to communicate with your origin. I see like ~95% cache hits with that turned on.

Argo does not affect caching, only performance. You're maybe mistaking it for tiered caching or a custom caching topology.

Yes, they call it Argo Tiered Cache under Caching tab.
