I've tried to create resources like this in the past for internal use in agencies and also mentoring clients and I think the thing that makes it really tough is that for any of this kind of information to be actionable the would-be SEO needs to get a grip on the creative and strategic elements. For example - I always found it tough communicating to colleagues/clients that it's one thing seeing a particular keyword on Semrush/Ahrefs that they'd like to after - it's another having enough experience to work out if it's something that's worth their effort based on things like their domain authority/core web vitals - and then again knowing what to do to go after it in RE search intent and how to out-compete the existing results.

Then there's the extra tricky bit that the kind of people reading these types of articles are often going to be small business owners/entrepreneurs who aren't necessarily going to want to put the time and effort into the above.

I don't mean this is a criticism of the original article to be clear. It's my own experience of trying to create resources like this that readers would be able to pick up and use to drive traffic (and ultimately make money). This article goes after more of a glossary-style approach, which is still going to provide value - knowing the lingo is really important for the kind of people who will want this kind of resource, if nothing else to help them understand what they're talking about if it comes to dealing with external stakeholders or agencies etc without getting ripped off. It's an inherently difficult topic to be comprehensive about in a blog post - if it wasn't, there probably wouldn't be so many people making good money as full-time SEOs.
