Assuming you give the voter's vote to their first choice and
automatically elect any candidate once he meets the Droop quota, then
the elimination method doesn't matter.

No matter what order you eliminate the candidates in the faction,
eventually there will be only one of them left.

That candidate will thus receive the faction's entire vote and since
the faction is larger than a Droop quota (by definition), the
candidate will automatically be elected.

Reading the rest of your post, I think you have come to the same
conclusion, but for single seaters.
