regarding levush, tzitzis, brachos and i’ll add using a yiddish name to the list.
If someone can show up to work with nose rings, tatoos, a hijab or a name like shaniqua, then obviously jewish attire, making a bracha at your desk (not sure about out loud, since you dont expect the goy to say amen) a yarmulka or a jewish name should be perfectly normal, acceptable and not out of place.
