After a little research I found a couple of detailed french door build tutorials.

Yet interestingly, Holden says
"French doors are simply doors with windows from top to bottom." By that particular definition, the doors from the OP would not be considered french doors. But maybe that's just splitting hairs -- with a 10" table saw blade 😁
From a historical site, "
Hôtel Lagrenée de Mézières" they accurately describe what I'm after as, "Opening on to the long veranda, the [high] doors have double shutters in cane netting to allow ventilation"
So in retrospect I'm thinking the "french door" may or may not be a part of the equation. In other words, some are, some aren't.
Mor pics I found:

I still don't know what to call this arrangement besides generically "veranda doors"(??) But the overarching design is:
1) Tall doors to allow maximum airflow
2) Usually covered by some kind of exterior louver/shutter to block sunlight, yet permit airflow
3) Doors behind this may or may not be double-doors. And they may or may not be "french" glass doors. (Judging by the stout hardware I don't know if the last pic has any other door at all behind it.)
