A pocket hole screw is just a screw at an angle. So if a single screw in each stud is enough, so would pocket screws.

The problem I see is that the top is only 1” thick. The screws can easily handle the forces. But, it’s bound to compress the wall board and the shelf itself slightly. So the shelf won’t fall off the wall, but I think it will sag. You could of course angle the back edge so it would tilt up slightly, then sag would level it, but how much you would need would be trial and error, and it likely wouldn’t stay level over the years.

I like your idea of sinking rod into the studs. Make these go into the studs as deep as possible and into the shelf as far as possible. If you get that level, I think it will stay level. The reason for going deep in both directions is to spread the forces over a larger are and reduce the tendency of the rod to compress the wood over time and then sag.

While the shelf is decorative, if it is within reach, someone will put their weight on it. Whether this is child trying to climb it, or your drunk brother in law trying to hold himself up, you still need to consider the possibility.
