We need to know what you're trying to build to give you a good answer.

Like CmonDev, I'm wondering why you chose this stack. If time is an issue, I'd suggest using a stack you've already mastered, even if it isn't fashionable. As long as it's not something weird, you'll be able to find other people who can work on it with you (and Java isn't weird).

Node is commonly used in hybrid stacks where the backend is initially written in something like Python, and then the REST API is written in Node to speed up requests. That takes advantage of Python's strengths and Node's strengths.

Also, the question of "how strong/versatile/useful is this foundation" is a really hard one to answer without real-world trials, and those take lots of time. I'd suggest finding someone who has written a framework using the stack of your choice and piggyback on their work. No sense reinventing the wheel.
