Would it be easier to learn Phaser 2 for a beginner?

Assuming documentation and examples are plentiful for Phaser 2. 

Or should I not bother and continue to try and learn Phaser 3?

I'd stick to phaser 2 CE for now. Even though quite hypocritically I regret not learning phaser 3 since I've gotten much better at reading docs while learning Phaser 2.

I also recommend starting with Phaser 2.  There's a lot more documentation and experienced support out there for it. It's not that hard to switch later.
