Infini is an ok floral, but didn't seem anything special to me. Parfum sacre is a spicy woody rose, interesting, but again, didn't wow me too much. I have En Avion in parfum: it's a dry, thankfully non-soapy orange blossom with fresh anisic note and a slight dry leathery drydown. I suppose it was more leathery and chypre in distant vintage, but it's still very good.
In your wishlist, I especially like Acaciosa, a rich, dirty jasmine.At least when I bought it, it was still ok, although with Caron one can never be sure of reformulation. I have not smelled NdN in parfum, so I cannot comment on that. The edt has a nice dirty note, but it also has a powdery-soapy note that ruins the whole thing a bit. Current NN in edt is an orange blossom of little consequence, and I haven't smelled the parfum enough to judge it.
As you've heard already, parfum is usually vastly better than edt for current Caron, and the way to go.
