If you remember little to no coding, I would honestly just try making console-level stuff first to get the basics down. If you remember at least some coding basics, I'd start with GameMaker. Make a few small projects in it, learn what you're doing, and then try moving to Unity or Godot when you start feeling limited by its capabilities.
A breakout game is definitely doable as a beginner project - it's actually a pretty good choice to learn with.
