A+
I don't know about the others, but when I got A+ certified years ago, it was pretty worthless. I did it in high school, got pretty much a perfect score, and learned practically nothing. May be worth doing if you don't have access to a personal computer, but you'd learn way more installing Linux or BSD on a couple of systems and doing some self-hosting.
You shouldnt work your hobby all the time
Unless you really enjoy it.
I self host all kinds of stuff with moderately complex configuration, and I find it relaxing after a day of writing code (I'm a software engineer by day). Cybersecurity is just learning to follow best practices and trying to break your own stuff.
Once you feel comfortable admin-ing something relatively complex (say, something w/ TLS, reverse proxies, and a VPN) and you have a day-job somewhat related to Cybersecurity, then you should look into the InfoSec community and read along with how exploits and whatnot work, and harden your systems against the various types of threats.
But honestly, there's really no substitute for formal education. If you like this stuff as a kid, consider getting a 4-year degree in IT. If you like this stuff as an adult, maybe do a master's program and try to land a relevant job.
