Best Enlisted AFSC/SFSC for a Long-Term Cyber/Cloud Career?

I’m 25 years old, married, and have a young son. I already have a bachelor’s degree, several CompTIA certifications (A+, Network+, Security+, Project+, and ITIL), and about 3–4 years of enterprise IT experience. My long-term goal is to build the strongest possible technical background in cybersecurity, cloud, and enterprise infrastructure.
Right now, I’m leaning toward the enlisted route because I think it may provide more hands-on technical experience than going in as an officer, but I’m still trying to make the most informed decision.
If your goal was to maximize your career after one 4- or 6-year enlistment, what would you do?
Which Air Force or Space Force enlisted career fields would you recommend?
What would you focus on while serving to become as competitive as possible for civilian cybersecurity or cloud roles?
Would you use Tuition Assistance for a master’s while serving, or save the GI Bill for after separation?
Looking back, what would you have done differently if your goal was to leave the military with the strongest possible résumé?
My goal isn’t necessarily to make the military a 20-year career. It’s to take full advantage of the training, education, certifications, security clearance (if applicable), and experience so I can transition into a high-paying IT/cyber career afterward.
I’d really appreciate hearing from anyone who’s been through this or is currently serving in a cyber or IT career field.
