I literally have THREE photos for myself on my Mac (macOS 10.15.4). This is frustrating:
SIMPLY PUT, CAN WE SYNC ALL ITERATIONS OF OUR MEMOJI ACROSS A MAC?

Memoji is not implemented in macOS.
You're only partially correct. This is a haphazard situation by Apple.
If you do not create a full name local user ID, it will spawn one or two contact cards. This was part of my issue.
Background: For a time - it was available. On two of my machines, I can see my Memoji as my user picture. On one, it (previously) synced my iCloud password.
But Apple got scared and stopped "syncing" Memoji with a local user account. Now, I just see plain grey in my Apple ID, not my Memoji.
That is, unlike Microsoft, Apple doesn't want someone to get locked out of a local machine, or have a network compromise impact any and all machines.
