@Natalie Weyant The idea of house hacking is to eliminate your housing expense while also purchasing a property that can be a future investment. It can absolutely be tough to purchase a house in such an expensive market so you'll need to weigh the costs of the money you're paying to rent a place and not be tied to it or responsible for keeping the place up vs. buying an investment property to live in and use rent to supplement your income while taking on the responsibility of managing a house.
I found it beneficial to buy because the rent from my other unit and bedroom covered by mortgage and also the house works as an investment once I move out. As for the condo/coop someone from your area will be better equipped to answer that, but in my area I typically advise against that.
Talk to local lenders, don't get stuck on the idea of just using an FHA. There should be plenty of other owner occupy and down payment assistance programs out there in your area.
