If you prefer video tutorials, all the tutorials from the Godotneers YouTube channel are imho easy to understand and quite clean (i.e.: everything is done the right way and explained properly).

If you prefer text tutorials, the official documentation is actually much simpler and complete than you might expect from previous experiences with other engines.

Also, if the only reason for you to dismiss C# is to not have to download .NET, I would recommend reconsidering. .NET is almost entirely open source, and it’s just a few hundred MB to download. That being said, I would still recommend trying GDScript first, as it’s easier and leaner than C# imho (which makes sense, since it’s a DSL).
