writing a Jewish original character while not being Jewish

for a couple years now, ive had a small set of original characters, and a storyline to go with them. one of those characters is Jewish. I’ve been dancing around the subject of writing that story and those characters because even after some research I’m still not 100% sure how to write and portray a Jewish character correctly and respectfully, given the fact that I am not Jewish, and don’t want to accidentally write him in a way that is antisemetic.

is there anything I should definitely include in his character, or little-known harmful stereotypes I should avoid? he’s also intended to be a trans man, is that ok?

I’m sorry if this isn’t the best place to ask, but I thought this would be the best way to directly ask how I should go about writing him.

any help is very much appreciated, thank you!!
