Why would Jews want to live as the Palestinians in the West Bank or Gaza, when that means living under occupation, being subjected to Israeli military law, being powerless against settlers violence and the prepotence of Israel? And what would they do, immigrate there from New York and start a farm, with a pinky promise that they won't turn into settlers and seek to join Israel?
And of course it would be risky, when they are so easily associated with the settlers and the occupying power- no point in denying it.
Nonetheless, there are entire large Palestinian clans that claim to descend from Jews and retain some of their customs: a famous example is the Makhamra family.
Jews who haven’t converted to Islam have been ethnically cleansed from the West Bank by Jordan when they occupied it, and this apartheid is maintained by the Palestinian Authority. Anyone visibly Jewish who enters areas under total PA control gets arrested (or lynched).
Why can’t Jews live under Palestinian authority the same way Muslims live in Israel? This racism has led to a situation where the only way the Jews of the West Bank can be safe is by having an IDF presence.
Your “fears” of Jews turning into settlers are no different to the Islamophobes who say Muslims who come to live in western countries will turn them into caliphates.
Anyway, there are Jewish journalists who have visited and spent time in Gaza. Here's Dan Cohen (precisely on the topic of safety of Jews in Gaza):

Then there is Amira Hass, who actually lives in Ramallah and has reported from Gaza. These are the ones I know, there are certainly others.
