It’s worth using a CDN to reduce server load and increase your website’s speed. Cloudflare is free for most use cases and ridiculously easy to set up.

But they insist on put your NS on cloudflare as well and afair not accepting domains greater than 2nd level.

Coming back to the load - simple 3vCPU Linux based VPS on Hetzner could handle 4Gbit of traffic serving. Offloading your server fleet probably the last reason here. Geo presence - agree here.
