Also if you really want to get into the meat of beginner stuff for free Unreal has a whole site dedicated to that. go here https://learn.unrealengine.com and do any course you think is a good starting point or interesting to you.
My suggestion is to start with the courses titled “Exploring Blueprints” then do the “Twin Stick Shooter with Blueprint” course as that one also talks about C++ with blueprints towards the end.
