Making maps accessible

Does anyone have good tips on how to create maps in accordance with WCAG regulations, or as user-friendly as possible for most people?
As a content producer for the public sector, we are very committed to delivering content that all our citizens can use. As far as I know, there are no regulations in place yet for universal design of maps, but nevertheless, we would like to provide map solutions to as many people as possible.

Any tips that can help us with this are greatly appreciated!
