Cosmic microwave background radiation is the earliest light we can detect. There is nothing to detect before that as far as I know.

Primordial gravitational waves may be detected one day.

I was just thinking about this. Are primordial gravity waves detectable in principle? If so, how much more precise do our detectors need to be to "see" them?

It seems so. But to detect them, you need a really big detector. https://en.wikipedia.org/wiki/Big_Bang_Observer

Some also suspect there are neutrinos still ripping about from the big bang, but we won't be able to intelligently detect and interpret those any time soon.
