It's a fitting job for xcoffins. It is a package created to facilitate the layout of stuff on the page: text, tables, images, graphics, etc., in a very simple way. Handy to construct cover and title pages, and cheat sheets...
It works like a graphic design program (almost, no GUI, you have to compile to see the changes) in the sense that it uses the relative positions of the objects, rather than absolute coordinates.
You put the material in special boxes that have several handles (in the corners, in the middle of the sides, in the center and others) that allow you to join the handle of one box with a handle of another box. For example, the lower left corner of the first with the upper left corner of the second.
On top of that, you can add vertical and horizontal offsets to position the content exactly where you want it.
I collected several tables, a list, a figure and a text (the title) and assembled all them (9 objects) using a large box the size of the text area, like a frame (called \Framex) to collect the others. I took several tables from the reference you gave from Michael Goerz refcards.
All the material will go on top of the frame.
After the nine joins are completed, the frame is composed on a single page.
I included a table with the dimensions of the boxes (using the tools provided by xcoffins plus a macro to convert pt to cm), before the assembly process. It might be helpful to build a mockup model with paper rectangles to find the best arrangement.
I recommend doing one merge at a time and compiling, to see how the box fits together and if offsets are needed. The process is very fast once you understand the name of the basic identifiers of the handles using the letters l, r, t, b, vc, hc.
I also recommend reading the manual on the package, replicating the example for a quick learning curve.

I do not claim to have achieved a nice design.


This is the code. Many packages are needed only for the tables.

Final note. I think that the problem of optimal bin packing does not apply to a reference sheet were the material should follow some logical order.
From https://en.wikipedia.org/wiki/Bin_packing_problem
Despite the fact that the bin packing problem has an NP-hard
computational complexity, optimal solutions to very large instances of
the problem can be produced with sophisticated algorithms. In
addition, many heuristics have been developed: for example, the first
fit algorithm provides a fast but often non-optimal solution,
involving placing each item into the first bin in which it will fit.
It requires Θ(n log n) time, where n is the number of items to be
packed. The algorithm can be made much more effective by first sorting
the list of items into decreasing order (sometimes known as the
first-fit decreasing algorithm), although this still does not
guarantee an optimal solution, and for longer lists may increase the
running time of the algorithm.
The xcoffins package could be used to implement any heuristics algorithm, like the next-fit decreasing height algorithm, as is shown here
