What are my career options if I major in atronomy? What kind of options do I have regarding careers and availabity/growth/wages?

As someone who once worked in astronomy and no longer does, I can tell you for sure that there is a major funding crisis. Whether you go the academic route or the industry route, the funding is largely from the same place: the US government. And they have no money for space these days. It used to be that you proposed some research or mission, competed with a few dozen colleagues, and won maybe one out of two or three grants you applied to. That's no longer the case. Now it takes dozens of applications in some cases to get funded even for a short-term project. So all that time is wasted writing proposals that won't be useful rather than doing useful work. Thus wasting much of the money and time you do have. Several astrophysics people I know are now in other fields. I have a PhD in space and atmospheric science, but I'm working as a software engineer because NASA (read: Congress) stopped funding research. I'm not saying that you shouldn't do it, but don't be surprised if you spend most of your time writing about research you'd love to do (and reviewing similar proposals from your competition) rather than actually doing it.

That said, astronomy isn't the only science out there, and some are better funded than others. Biomedical is booming, for example, as is chemistry. A strong grounding in basic science can also land you an engineering path, or good critical thinking skills that can even be translated to journalism or other widely varied subjects. So I'd suggest you continue pursuing science, but broaden your focus from astronomy. A lot of my friends do that as a personal hobby while working in other fields, so you can still get enjoyment out of it while NOT spending all your time doing grant applications. (Oh, and the pay does suck, at least on the academic path.)

Go to: Californiacollege.edu or https://www.onetonline.org/

Look up your field on either website. The californiacollege.edu website will tell you the relevance of your astronomers. The average wage is $105,410 a year. In addition, there are several teaching opportunities when have advanced degrees.
