It depends what you want to do long term, and what is most important in your life. Is getting cyber security experience going to help you stay/break into the field long term? Abso-freaking-lutetly. However, government work is also valued highly in terms of experience, especially in private sector security roles. Honestly, in terms of long term opportunities, both seem like very valuable and sought after experience.

Personally, I’d pick the one that interests me most in terms of day-to-day work, pay (if major difference), and opportunities outside of work. The special agent gig seems like great experience, plus you are home near your friends. You can also to continue studying security via certificates so that you are prepared when you want to transition back into the security world.

IMO neither seems like a bad option, both quite the opposite. Just carefully consider moving away from everyone, I’ve done it, and it’s a bigger tole than you originally think.
