Open Apps with Siri
Siri can do all kinds of things on your iPad, but one of the most useful is opening up an app so that you can use it.
If you hate looking for an app or searching through your apps, you can use Siri to open the app.
Press and hold the home button, or say "Hey Siri" and then say, "Open app name."
The iPad needs to be unlocked, but that's about the only limitation. You can't take a lot of in app actions, but at least you can say, "Siri open Spotify", and then you can tap on the music you want to hear.
You can also create Siri Shortcuts that allow you to create specific actions inside apps and across apps when you set them up yourself or when you find a shortcut that someone else has created. Check out the Siri Shortcuts app on your iPad to get started.
