NYC native here. Not for everyone. How much have either you been to NYC? "Dream to live there" really makes me suspicious of not actually knowing what it is like there.
Some people love it. Great! There are some cool qualities to NYC, but it's a unique place. I moved away and def couldn't live there again. Your qol will go down bc it's so expensive. So consider it as taking a major pay cut to go to NYC. If you're okay with that, cool.
fyi The subways smell like piss. All the time. I don't want to smell gross piss every day. That was enough for me to let it go. But there's other reasons.
Good luck regardless. I second the don't bring anything advice. Minimalism in your living space is your friend as every time you go out you'll be bombarded with stimuli
