Any education has benefit - to leverage these online courses into getting a job, you will likely have to use that knowledge to build a portfolio (eg, for web development).
Apart from the portfolio case above, places I’ve worked at are only interested in them for people who already have degrees, and are looking to specialize or shift their area of focus (eg, computer science degree holder wants to do ML, so we will look at additional online ML/maths/stats courses as a positive on top of their degree).
I am sure that there may be some places that place value on simply
completing these courses alone, but if you want to produce a “formidable” CV, I would look at your degree options.
