Just LinkedIn people at senior levels at your company and see what schools they went to, that will help see if you are wasting money. The fact that you understand you need to do more schooling puts you ahead of the game
I'm working at a military base on a DOD contract, and most of the people here are former military or federal government employees, so I'm not in a position to network like with a "normal" gig. Like I mentioned, as long as the school is accredited, I'm good to go. I just need the degree title for real.
Education will be the cheat code for me. This contract is 3 years and hopefully by the end I'll have a public trust clearance, an M.S, and certification in project management. I'm also trying to open my own contracting business, so that I can eliminate the middle man, but if that doesn't pan out, at least I'll be employable. There are some other certifications I plan to get as well that tie in directly to what I'm doing and the company i'm working for pays for that, so i will take advantage.
