I remember this question was actually helpful, but search results are a bit outdated, it would be nice to have some new responses.
The real answer is it depends on what job you’re applying to. Boating license can be done online in some places (not free usually but cheap). There are some naloxone training courses online that can look good (usually free).
IT certifications are good, can usually be done online. Data science/machine learning/programming online certifications are not credible at all. Some of the bootcamps other people will give weight to but I’m always skeptical.
Also fyi I would not consider an online first aid course to be valid training as the physical training is really important.
