The ones I feel I get the most out of are the text to speech reminders that play in the whole house with all of the activities and chores that needs to be done.

Kids laundry days, activities, unpacking clothes, homework etc.

Reads everything from a shared Google Calender.

Automating the kids evening routines is also a good one. Cutting of the network access to TV:s and reminding them it's time to go to bed.
Always there and help them with it but it cuts down on nagging and the argumentation surrounding how long they have watched TV and so on.

Putting on their evening music on a timer, adjusting the volume, lights.

Besides that and the regular lights on/off routines in the whole house the presence simulation when we are away is also a good one.

Having problems with getting object detection working on the Yellow via Google Coral though, rumours say it's doable but no one has actually got it working so I am starting to think it's BS.
