Working for the government is always a useful way to make a living because it is rare that a government role shuts down. Get yourself in a government position and do the job right, and you could be enjoying years of progress and success. With that in mind, then, I recommend that you look into working with a skills assessment team.
For example, if you are looking to work for the Australian government, you could look into a company called atWork Australia. As a disability employment services (DES) expert, they simplify a lot of the questions you might have. You do not have to be disabled to get help from atWork; simply disadvantaged. This means that if you are looking for help finding meaningful work in the government sector, you can turn to them for an interview.
I was able to learn a lot about the skills I have and the skills I lack. That was pretty useful in the long term; it helped me to just feel a bit more confident in myself. I also now knew what path I had to go down if I wanted to get better and find long-term work. These were questions I had long sought an answer to, and my atWork interview opened a lot of doors in my mind.
Working for the government is something that I never managed to do in the end, but that is because I found another job in a different sector. However, I now have the skills that I would need to apply for a government role and have a chance of being selected. My advice, then, is simple: get in touch with atWork. Arrange an interview, and see where you lack in terms of skills so you can seriously target that government position in the future.
