I've had a great experience making use of the Unity 3D free premium learning courses (free until June during the pandemic) with my youngest child.

Like your child, mine didn't care for Scratch. He's loving Unity though. Actually, who am I kidding, I'm enjoying immensely too. We've laughed our heads off together tweaking and adding small features to the rudimentary games that their basic course guides you through.

This is the basic course if you're interested: https://learn.unity.com/course/create-with-code-live

The Usborne books you linked to sound interesting too. I'll be sure to check those out.
