I started with babylonjs about two months ago. To my knowledge there is not necessarily tutorials for what you are looking for, but the documentation is so rich that you will find all the information to get started. Here are some links to start:
- cameras:

https://doc.babylonjs.com/how_to/multi_materials
https://doc.babylonjs.com/extensions/terrain - some ideas for buildings creation :
A nice new addon for Blender 2.8+ for creating buildings - #5 by gryff
Basic Skyscrapers from footprints and Scifi Textures
Examples from the playground - #582 by HiteshSahu
