My advice is do two things:

1) Start something of your own. Get doing social for yourself or a friend or reach out to an influencer. Anything to get some credibility and real world experience. There’s a difference between reading and taking courses and actual hands on experience.

2) The certifications you outlined (for the most part) are good. I wouldn’t pay for courses from third parties (ie not the platforms). Facebook Blueprint is a great place to start. TBH – If you’re FB certified and can actually run ads you should be able to get a job. It’s in high demand.
