What a good cert to pursue is whatever interests you.
IT is as wide a field as medicine, law, and automotive. In medicine, you can be a general practitioner, or you can specialize in pediatrics, geriatrics, oncology, rheumatology, cardiology, etc. In law, you can go into criminal, divorce, bankruptcy, corporate, real estate, labor, and so on. Automotive is equally as wide in breadth and depth.
In IT, you can go into networks, security, programming of all flavors, management, database…you name it.
With a year and a half under your belt, you’re barely scratching the surface of everything that’s available. Don’t focus as strongly on just achieving certifications as spending that time instead on getting your hands dirty. You’re doing network troubleshooting and repair, which is much more valuable than the certs would have you believe.
Personally, I’d rather hire a network tech who’s punched down a CAT5 drop and can run a wire above ceiling tile, and knows what a bridle ring is, back to the IDF and punched into the panel, then knows how/why to use a continuity tester, than someone who’s memorized the right answers about cable length for the exam but has never actually done it and gone home to take a shower to wash off that ceiling dust out of the hair. 
Anyone can memorize answers. Not everyone can run structured cabling, because that’s the kind of thing you can’t study out of a book.
You say you don’t know what specialization to pursue? Don’t waste your energy looking for “generic” certs that may or may not serve you professionally in the long run (because remember that CompTIA certs require recertification every few years, so if you’re not actively pursuing those fields, those certs will do you no good if you end up not renewing or not qualifying to renew)… Spend that time instead trying out different things, and THEN find what appeals to you.
Could be databases, could be programming, could be pen-testing. Could be Cisco CLI. Could be ANYTHING. You won’t know if you don’t give it a shot, a real world one, and not one based on questions asked on a multiple choice exam.
