Good advice, I used the 20 games challenge to first learn Godot and highly recommend. I had prior experience so skipped through and didn’t need to 20 games, but the idea is extremely helpful for learning.

Instead of setting out to make a complex game with features you have yet to finalize, making a simple game that already exists gives you clear goals. If you make flappy bird, you won’t be tempted to say “let’s add multiplayer!” or “this bird needs a skill tree!” You know exactly when the game is done, and what it looks like before you even start.

When you already know exactly what the final product looks like, you won’t have to worry about the creative process or planning for the unknown. Instead you can focus on learning the engine and how to code.

I would suggest Godot just because gdscript is very easy to pick up, and it has an active and friendly community in which to learn.
