If Napoleon during it's campaign had suported the creation of a Jewish state in Palestaine during it's campaign in Middle East would this would be beneficial for him?
You'll first need him to be able to do that, meaning he has to succeed the Syrian part of the Egyptian Campaign which he failed in OTL. And that is something that will be hard to do, especially after the French Fleet looses the battle of the Nile.
Furthermore, I doubt he would try to do that : it's too dangerous for him as it could angered all the Arabs in the region (meaning not just those loyal to the Ottomans) and turn them against him.
It's not a good example, but look at OTL Israel : there were many Arabs who weren't happy with the creation of a Jewish State. It's not a good example as it was 1947 and the mentalities were not the same as 1799. Nervertheless, you propose creating Israel two hundred years before its creation in OTL, a time were religious authorities had far more power than today, even though i'm not sure it will be all about religion.
I hope I'm not sounding racist or something similar because that is not what I intended to do. If I was, I'm sorry.

An ally that most likely wouldn't be able to support itself against the Ottoman Empire wouldn't be much of a benefit. Not to mention that modern irrigation techniques weren't available, making such a State quite less viable.
That's true and adds one more reason for Napoleon not create a Jewish State : it would be useless and fall in a very short time.
Besides, while it's true that Napoleon emancipated the Jews during his reign, I doubt he would have gone as far as create a Jewish State.
