Actually the Jews in Poland left suprisingly little, the genetic research backs up history, Jews and Poles did not mix.
There was an odd Jew who became Polish, a few of them went on to become notable on various fields but in general both population lived side by side but not mingling on a more intimate level given how insular Jews were.
So no, an example of a Pole who has even one Jewish member of his family sometime in the past is exceptionally rare.
Another case is that some Jews polonised themselves relatively late but their numbers probably dont exceed thirty maybe forty thousand people in 38.5 milion country.
As for civlisation, Polish culture and civilisation borrowed heavily from Western traditions and married them with its own so even here Jews did not contribute anything significant.
The topic is just off it rocker.
If I remember correctly, it said that thousands of Poles have discovered in the past decade that they are Jewish or that they had very close ancestors who were Jewish
4000 to be specific, there's sites and associations that are busy with that, approximately 4000 Polish citizens re-discovered their Jewish roots, again from a country of 38 milion people, hardly basis to speak of Jewish roots of Poland.
