@scarlett I see what you're going for. Your key points of interest will be axis-locking movement, figuring out your perspective and scale, and then starting to tinker with some assets.
The 3D asset workflow is garbage everywhere unless you're a pro. Blender->Godot is pretty good as things go, but it's still a PITA and buggy as hell. Texturing/materials is a nightmare as well.
If you really want to dig in and not have to spend the next 2 weeks learning how to model and rig, get some itch assets
