Perhaps there is one overall connection-management process that
accepts all new connections; if not, another worker that has that
socket can pass it along.

That’s not how you do it. You pass it with the SCM_RIGHTS
ancillary-data option in Unix-family sockets
<https://manpages.debian.org/7/unix.7.en.html>.

 
Worker A has a AF_INET socket to client so what AF_UNIX socket does it
pass to worker B?

You can pass any FD (AF_INET socket, file, pipe, even another AF_UNIX
socket) over an AF_UNIX socket.
