Is there some demo available somewhere, to use to present SharePoint for a company? With some fictive departments (Economy, HR...and so on), and with fictive employees with their access rights? So I could for example "log in" as an economy department member, and I see only economy related stuff?
For example, some collection of Excel files easy to import to SharePoint.
If you are a Microsoft partner they have 90 days demo tenants that you can order and be up and running in a few minutes with demo data and everything. You can find it here: https://demos.microsoft.com
there are some companies working in sharePoint implementation projects , you may contact any of them and they may provide you with this demo.
also you can subscribe in Office 365 Enterprise E3 trail (30 days) SharePoint online included.
You can also try pnp starter kit for getting some sites up and running with nice WebParts and some fictional sites.

In this moment i think your tenant has to be in Targeted release since atleast 1 WebPart is using the beta calls on MSGraphClient.
There are several Microsoft Labs available: https://www.microsoft.com/handsonlabs/SelfPacedLabs#keywords=sharepoint&page=1&sort=Newest
Hope this helps! Ova
