Opening Cubase 10 Pro for the first time - what to do next?

I am rather experienced with lots of DAWs but haven’t used Cubase much and not at all the past many years.

What are the cubawe-specific stuff/abilities I should look into when starting out? I come from primarily Logic and Live 10, Max/MSP.

So far I have bought Metagrid and am looking at Halion.
