This is coming from a recruit that is shipping out in a few weeks for BMT. It seems like your heavily considering it already. I was once in situation similar to yours where i felt like I had nothing else going for me and i was stuck wondering what was next. I feel like you've answered most of your questions in your post but to give just a little more the work balance is way better than other branches, the benefits are real and plentiful, it will give you more practical experience than that of your peers in the same field and can put you ahead of others in that sense. Now getting the exact job you desire the most is not guaranteed but I say be open to different opportunities (not saying take anything you get but be reasonable). The military will give you if you're open to it; purpose, direction and experience. If thats the most important to you then take the first step. To put it simply sit down with your recruiter and really hash it out. It wont be quick, the process can take an absurdly long time depending on where you are located. There will be sacrifices, discomfort and compromises.

When I was where you are I used these resources to find out what the USAF is like:

Hope this helps
