Need help in choosing product

Currently i am having server (hetzner) in germany with 1gbps port
but unfortunately there is alot of routing issue between my country and germany.
i dont want to leave hetzner as it is cheap.
so i am looking to get CDN for my server.
I basically run it for online lecture.
So, tell me which product of cloudflare should i use?
it should be cheap.

If it’s video, then take a look at Cloudflare Stream.

actually i am on webrtc it is not that streaming
