Not quite. Cloudfront predates Global Accelerator and has all its own infrastructure/routing/etc to answer client queries, get them to a nearby AWS pop, and return local content or fetch content from your single origin.

GA is similar, but more like a global anycast routing layer/load balancer. You can have multiple backends, different regions etc, use a single public GA endpoint, and GA will route the request to your nearest backend.

You could use a GA endpoint as an origin for Cloudfront, I guess, to keep all traffic as near to the client as possible.
