Online certifications and degrees are of exceedingly low value, and are often outright scams, unless the online degree is from an accredited university and is indistinguishable from any other degree offered.
Immersive coding boot camps, as much as I dislike the idea, do have value. If someone attends an in-person, full-time (40 hours a week for 12 weeks) bootcamp, from a reputable provider, that can actually lead to a job.
For young people, and those of limited means, I'd stop worrying about certifications and simply help them learn. Plenty of online resources are cheap and valuable, like udemy.com (to name one; there are many good ones). It's a good way to get started part-time. They can learn the basics at their own pace. They'll learn skills that employers will value, although it's unlikely to lead directly to a job.
No one should invest any serious money in education until they know if they like it and have the aptitude.
