It seems you would really like this group of Calabrians to be Jews of some sort, but I have no evidence to that effect. Until and if you have some, perhaps it's a non-starte, although of course I'm open to any such evidence anyone produces.
It's a mistake to attribute close FST to actual direct lines of descent or inheritance. It can result in false interpretations. Close fst can result from admixture of the same ancestral components in roughly similar proportions, that occurred in different places and times.
FWIW, the "Turkish Jews" have a lot of Sephardic Jewish descent, as in exiles from Spain and Portugal.
The Canary Islands are "dead red" as well, and other than their extra SSA, they're Iberian, so maybe it's something Iberian like, and therefore WHG and Yamnaya like which, with their very high Minoan like farmer component, makes them draw together.
The other part of their ancestry is from the Greek and Roman classical area. Who knows how much of that ancestry these types of Jews absorbed? Maybe they are the Jews responsible for the higher "European" of the Ashkenazim.
