Don’t spend too much money on certs. Employers should be paying for that. Maybe get Sec+ on your own dime (or if you can get your current employer to pay for it), but hold off on the more advanced and expensive certs until you find a job that pays for it.
The homelab is a great idea. If you want to get into a SOC role, maybe try setting up security onion, alienvault, ELK, or any of the opensource log analysis tools out there; and you can use the experience to demonstrate your knowledge on interviews.
