Yep, safe and you won’t need light rail for your commute. Just path to nyc. That will be a piece of cake for you. Light rail you can catch downtown if you need it for some reason.

There is also via, which is a subsidized ride share system. 2 dollar rides if you want to go to west side , Bergen Lafayette or the heights.

Pro tip you can take it downtown if you set the address to near the jersey city medical center
