I have some light wiper scratches on a windscreen I'd like to improve, can't be felt with the finger nail
I tried some car pro ceri glass and a foam pad in a drill but this wouldn't touch it.
Any recommendations for some paste or a kit to use or am I wasting my time?

I've tried before, like you no improvement. I reckon it's one of those jobs where you need a knack.

Wiper marks usually cannot be felt with your nail because they're more like a scuff that's been worn in with the continuous wiper sweeps. When polishing, the lighter marks start to disappear revealing the deeper ones. It can sometimes look worse. If there is a deeper gouge underneath all that, getting rid of that will lead to distortion.

There aren't many glass polishing specialists who will want to take a wiper scratch on.

Ceriglas is effectively the same as jewellers rouge in that it’s cerium oxide.
You’ll need rayon pads to use in conjunction with it. Even then it’s a very laborious task, be careful with heat build up when polishing especially if you have any stone chips.

I'm not getting too hung up on it, it's my garage queen and you can only see it when the light shines on it so no big problem.
I will give it go with the rouge and move on.

No.

Depending on the damage, graduate to 3000 grit sand paper in stages, then Cerium Oxide.
