Hi Fauntail,
The short answer, have a look here:
https://www.cineversity.com/learn
Your questions:
Please use the right mouse click option in the application itself, it leads directly to the content needed. It might help as well to get the specific terms in question.
The oldest videos have certainly the disadvantage of using the interface of the, back then, current release.
The “whole picture”, that is a larger or perhaps just a simple question. I guess the link above has given already some insight. I will go more in detail below, as it is your target that should be known first.
More in depth and why such a general question would really fit the individual needs:
I tell you obviously nothing new, but since we talk in a forum, a common request is, to come from one application and want to find in the new application similar tools. This is certainly a nice idea, but it might also block the view of how things are done in a specific app. Modo, coming from Light Wave had certainly some new ideas to overcome LW, hence why the guys had split from LW. No one would really expect in Modo to have everything as it was in LW, whats the point then, right? C4D is different as well, and sadly, we have no training for Modo users targeting now C4D.
I have explored over the years how people learn, and tried to classify this. Not to judge the content, more to see what works with one and what with other artists. There is no one size fits all. However, I think that most material that is really needed is just all basic, there is not a lot advanced stuff that would allow for being on the top. The most brilliant artists results
or solutions are clever combinations of such basic things.
Advanced is mostly based on combinations of those basic functions, options and tools. Typically, so my experience, people don’t like to do extensively basic stuff, but it pays off after a while. Jumping over it, perhaps with some “advanced tutorials” gives only the illusion of making maximum progress; It’s more often than not a “paper tiger”. So, even you tell me you are intermediate in your skill set, the truth will be that you have some very high skills and understandings of the matter in some fields, but also some areas with less perhaps.
HERE exactly starts the problem, every single artist has a different mix, every single one. As you certainly know as well, the needed knowledge is not limited to the tools of an application. Problem solving strategies and mathematics, knowledge in many specific areas as well comes to mind. Think of architectural visualization or medical viz, besides Motion Graphics, to name only a few.
So, whatever I can suggest is just a guess, not knowing you and your background nor target. For that we hope that the search options and filter options in the Cineversity interface will help. But that is of course only a fraction of the idea behind Cineversity.
The answer that Cineversity has for all of these things, is: specific series, playlists, and the forum, as well as 1on1 training. As I mentioned, there might not be anything that fits 100% given the huge variety what our artists here needs.
All of that said, every artist has a different pre-knowledge, and a different target. No one learns an application completely anymore, just in case. At least I have seen anyone in the past two decades who knows everything, and I used 3D longer than that. Which leaves me to ask, what is your target? With out that, I might waste your time.
As a personal note, I read the manual many times since the mid 90s, and from time to time I browse the Main menu>Windows> Customization> Customize Commands. Here is a long list with pretty much all, except some parts, like XPresso for example.
The Quick Start Guide from MAXON delivers via a quick read a good first impression.
Perhaps take a little bit time and enjoy the presentations from next weeks NAB on

After that, I hope you have a ton of ideas what to explore. 
Enjoy your weekend
