French ciders get a good part of their character from the way they blend different types of cider apples. They use very little apples that contain acidity - I'd say maximum of 20 to 25%, and often less than that.
Hence about 80% of their blends consists in douces, douce-amères and amères (respectively equivalent to sweet, mild bittersweet and full bittersweet) and the rest would be acidulées and aigres (mild sharp and full sharp). They don't use acidulée-amères (Bittersharp) in France.
As of your question about "sweet", yes it means low acidity and low tannins - but although low in tannins these apples do contain more phenolics than common apples, albeit less that the other categories.
From you list, most are sharps. You only have a few bittersweet varieties (Chisel, Tremlett, Brown Snout, Ellis Bitter) - hence you need to make 80% of your blend from these and the remaining 20% from the others... Note that this wouldn't give you a real French cider, but you'd obtain similar acid-tannin balance.
