I found a good picture / poster with an overview of D365 apps and functions. It is really good to look at when having a discussion or brainstorming session with customers.
Is there any official poster like this?

Hi,
I did not find exactly what you are looking for, but I would recommend you to take a look to this learning process. Here you will find an exceptionally good description of those apps:
Microsoft Certified: Dynamics 365 Fundamentals (CRM) - Learn | Microsoft Docs
