FYI, DCL has updated their policy section on "Providing Proof of COVID-19 Vaccination and Negative PCR Test", specifically as it pertains to "vaccinated Guests arriving from outside the United States ": <bold below is added by me to highlight the new information>
Voluntarily Choose to Provide Proof of a COVID-19 Vaccination
Guests who are fully vaccinated may choose to provide proof of vaccination in order to be exempt from pre-arrival and Embarkation Day COVID-19 testing (unless arriving from outside the United States). The US Centers for Disease Control and Prevention considers people to be fully vaccinated 14 days after the final dose has been administered. Guests may visit the Safe Passage website beginning 33 days before—but no later than 24 hours before—sailing to upload an image file (PDF, JPG, TIFF, etc.) showing proof of vaccination, preferably a vaccination card. For Guests choosing this option and to be exempt from certain policies on board, it is recommended to bring proof of vaccination (vaccination card) to the port for embarkation. Keep in mind, vaccinated Guests arriving from outside the United States who are required to undergo the rapid test on Embarkation Day will not be charged for the test. Additionally, travel insurance is not required for vaccinated Guests arriving from outside the United States on sailings originating in the United States.

I did NOT find anywhere where they address the issue of which vaccines they consider acceptable, including whether those who have so-called "mixed doses" (either two different brands of mRNA, or AZ followed by an mRNA) would be considered acceptable.
Personally, if I was in the situation of having been vaccinated outside the US, I would want to verify with DCL myself, in writing, whether the vaccines I have are considered acceptable or not. And if I was "arriving from outside the US" I would also want to verify the above in bold is correct since it is a change from the previous wording.
For our family, we never step foot in the US without travel insurance anyway, but I understand others may choose otherwise.

Thanks for posting! It's good to see some clarification.
From reading this, it appears that my question to the CM was not addressed. I guess I can assume "arriving from outside US" still means non-US citizens/residents and not literally "arriving" since some US citizens could be living in a different country.
And that if I'm at WDW for a week prior to my cruise, I would still need to get the pre-test regardless if I'm a fully vaccinated Canadian.
