The FEP doesn’t currently point to this Discussion Thread (code).

It points to the issue tracker, but this thread can be used too.

My understanding is that a Generic ActivityPub Server would function similar to an ATProto PDS.

Yes, it is similar to ATProto PDSes and Nostr relays.

I’m curious on how this compares to projects like rdf-pub, Vocata, and ActivityPods.

These projects rely on linked data processing. This FEP attempts to solve the problem with JSON only.

Unfortunately I don't know enough about these implementations to provide a more detailed comparison.
