Question on fitting this countertop.

The wall on the right isn’t square and I’m trying to figure out proper way to fit this.

Option 1: the gap at the front is 1/2” so if I start a cut 1/2” in from the back angle to the front corner it should then fit properly. Right?

Option 2: I’m putting tile on the wall there anyway so I could just “send it” and the tile will hide it.

Option 1 seems like the “correct” way, I just want to make sure I’m thinking correctly before I start cutting since I can’t add wood back on.

Thanks!
