Points 3 and 4 are good, but they didn't intentionally fuck the planets over. Nor do I think jews are known for theft at all, unless my antisemitism.exe and racism.dll is very outdated. That is gypsies and niggers.
Jews are known for trickery, so a Tzeentch faction or such would be the best bet. Like the Pajeet they trick you out of your money, not steal your money. I remember that Jonah had a 4chan joke that the Blood Ravens loved him because his melanin helped him get "gifted artifacts" even better, and they had an elite squad of black space marines to aquire loot from other chapters.

Not sure but are jewish ancestry a hotly debated mystery? Outside of DAS RITE Black Hebrew Israelite circles, I don't think so. They are just semites, its not like they are the sea peoples of the bronze age collapse or hungarians who have a less well documented history. If we want to keep it to imperials, radical inquisitors would fit the bill best.
Fink and radicals both want to "fix the world" by the most assinine and self-defeating ways possible. So radicals tick points 3,4,5 and 1 is more of a hungarian*/etc thing, 2 more of a nig/gypsy thing. They can also be tricky, and you can draw parelles with stuff like "inviting a million muslims---> Synagoge goes boom" to "plays with Chaos ---> planet gets eaten by demons".
* And a lot more, but well, the sea peoples are gone and we don't even know what they called themselves, and various injun tribes have hotly debated origins too.
