Vis a vis shidduchim, ,ultimately, it’s not as important where you live as who you know and who knows you. Do you have people to visit in various communities on Shabbos and Yom Tov? A boy could be learning in a totally different city, if it’s besharit, it’ll happen. But you do need to consider which communities will be supportive of wherever it is you’re holding, and will encourage you to continue to grow.
Still voting for Queens, Passaic, and yes, Far Rockaway is a great choice too. However, they come under the “Queens” umbrella, even if they don’t admit it. If there were a way to private message on YWN, I’d be able to extend an invite to you for a Shabbos in my community (which is outside of Brooklyn, of course).
