Unfortunately there is no up-to-date documentation. Over the years the rendering became more complex and the documentation was hardly ever updated.
You are now only talking about the rendering, but also the way the maps are built can reduce or enhance the rendering options. The most up-to-date information (and I specifically do not say documentation) can be retrieved from the github repository: https://github.com/osmandapp/OsmAnd-resources Check the renderiing_styles and obf_creation (less important but in case you do decide to create your own maps). >From a usage perspective, which is not rendering as such, but might be helpful as well in some little tweaking, you can take a look Bart Eisenbergs's youtube videos about hiking. They are really very informative. See https://www.youtube.com/user/barteisenberg. Also there: the latest ones represent current OsmAnd options best. Also: From the map menu when selecting "Configure map" (the two "layers" tiles on top of each other), you can add extra overlay or underlay maps. There are a lot of (downloadable) overlay/underlay maps available (no, not OpenAndroMaps Elevate. I just checked). Maybe one of those might suit your needs.
