Yes I see that.  I swear that at the beginning of this when I first used
insert-char to add FE0F after 1f37d they didn't compose, but I
can't reproduce that now.

Ah I was confusing default font with default fontset.

And I gather that something is loading Apple Color Emoji into my
fontset when I type something emacs thinks it can display.
Because if I do describe-fontset in a new emacs -Q Apple Color Emoji
isn't there, but if I insert the man emoji (which displays) and do
describe-fontset again Apple Color Emoji is there.

Thanks, I think I'm caught up now. Thanks for the all the handholding.
