The big benefit of raytracing now, imo (which most games aren't doing), is that it frees games up to introduce dynamic destruction again. We used to have all kinds of destructible walls and bits and bobs around, with flat lighting, but baked lighting has really limited what devs can do, because if you break something you need a solution to handle all the ways the lighting changes, and for the majority of games they just make everything stiff and unbreakable.
Raytracing is that solution. Plug and play, the lighting just works when you blow stuff up. DOOM: TDA is the best example of this currently (although still not a direct part of gameplay), with a bunch of destructible stuff everywhere, and that actually blows up with a physics sim rather than a canned animation. All the little boards have perfect ambient occlusion and shadows, because raytracing just does that.
It's really fun, if minor, and one of the things I actually look forward to more games doing with raytracing. IMO that's why raytracing has whelmed most people, because we're used to near-flawless baked lighting, and haven't really noticed the compromises that baked lighting has pushed on us.
