Rez is a great game to sit and relax to.

RE Village is beautiful and glorious.

Light Brigade and Cosmodread are both fun roguelike games with very different executions.

Call of the mountain is a great showcase of what the graphics can look like on PSVR2. Mostly a climbing simulator, so don't expect too much from the combat.

Regarding cable management, I just turn to the right so my cable goes off to the left towards the TV. I generally have plenty of slack in my cable, though I don't exactly have a large amount of space, your set up will likely vary. Make sure you're facing a wall with good contrasting items and not a lot of reflective glass. It might help to pick up a small IR light, I got this one and just plug it into my PS5 so it has power while I play and turn it towards my reference wall.
