The docs are honestly pretty good https://docs.godotengine.org/en/stable/getting_started/introduction/index.html

Are you looking at 2d or 3d?

The official ones ("your first 2D game" and "your first 3D game") are quite good and to the point - they are already linked in the thread. GDQuest is also nice, I remember them having this whole in-depth interactive course.

Usually tutorials are in GDScript, so I'd go with that. Plus, according to a recent poll, about 80% of Godot users actually use GDScript over C#.

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).
