wether third-party apps include built-in shortcuts that automate app features depends on their developer.
Open the Shortcuts app, create a new Shortcut and then switch to »Apps« to see the apps listed which have registered to Shortcuts.
Click on an app name in the list to see the commands it provides. If the apps you’re interested in offer shortcut support - in your case “use bluetooth” (or not) it will be displayed here (if I understand correctly what you want to do?)
If you just want to turn off bluetooth when arriving home: create a new shortcut which just uses Shortcut’s »Set Bluetooth«-command to turn BT off. Give it a name and then create a new automation which runs this shortcut when your iPhone arrives home. Create a second shortcut to turn BT on (again just the »Set Bluetooth«-command, name it, and run this in a different automation when your iPhone leaves home.
