Technical Best datasets (bin or binpack) for NNUE training?

Do you know where to find the best datasets that contain billions of positions with reliable scores (from strong and recent engines) that I can use to train my NNUE from scratch?

Ultimately I want to self train, but I need a strong basis that I can't generate with my engine in its current state (~3k elo).

3k is way stronger than needed to generate good self play data.

I also wouldn't call it from scratch if you are training based on another engine's data. I understand in ML it would still be considered from scratch, but I think in the computer chess community that wouldn't necessarily be considered from scratch.

Just do selfplay so that its your data and is unique, and the community will like you more.

Stormphrax did nnue iteration starting from a random net so at 3k elo your engine is way stronger then it needs to be do generate good scores.
