If I understand what you want yes the code does exactly that. You set the categoryDescriptionMap variable as described and when you go to a defined category page a description is displayed.
This code will not address any other the other items you mentioned.

Not sure what help you're asking for. What I did for a client with a lot of products was figure out the best way (from a prospective customer's point of view) to organize the products into product pages, and within those, into categories. I added tags to make it easier for me to filter products for blog pages and summary blocks. This can be hard work, but it's just part of the job. Some 7.0 templates make this easier than others. See https://www.phelpsrefinishing.com/ for my example. The Bedford template I used makes it easy to navigate categories within a menu item.

I have made several calls requesting more efficient organizing of products in catagories. Right now I was informed SS has set it up so that products need to be manually organized in thee different areas from most specific sub-category, catagories and  "All".  It is quite insane!
The answer it seems is to have the organize individual products in sub categories, move entire sub-categories within catagories (drag and drop) and then have this organization reflected in "All".
The current system is a deal breaker for anyone who has to move a lot of individual products.  I would never have started on SS had I know that organization would be so stupid and convoluted.
