I remember this question was actually helpful, but search results are a bit outdated, it would be nice to have some new responses.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.
Being a religious officiant is an easy credential. In the US at least.
Mind exposing what this is and what it’s used for?
You can perform weddings!
There’s the Universal Life Church, the Church of the Flying Spaghetti Monster, the American Marriage Ministries, and I have no idea how many others.

free but you can pay for certs for a bunch of them too: https://ocw.mit.edu/ https://www.businessinsider.com/guides/learning/free-mit-online-computer-science-classes
Depends on your area if it’s free but you can never go wrong with CPR/First Aid
I don’t think anyone has ever regretted having CPR training.
It might not be the most important thing to have on your CV, but you never know when you’ll need it and if you ever do it’ll be the most valuable thing in the world.
Actuarial certifications, you can go from unemployed to 70k entry level job with just the FM, P and FAM certifications. Get the other ones and enjoy an easy six figures job.
Actuarial exams are as far from free online certificates as you could possibly get…
