Godot is my goto engine for 2D and 2.5D stuff. It's fairly easy to pick up, it's free, and open source, and there's plenty or tutorials for it.
It uses GDscript which is a python like language, so it's not too difficult to learn. That's usually my recommendation to newbies.
But, I'd say try different things, and you'll figure out what you like personally. You may find something totally different suits your personal taste and interests best.
