question What is the best way to identify valuable expired domains?

any pros?

I like searching from oldest to newest .com 18 letters or less, gl.

If there is a lot of bidders for a certain name, that is a clue that either that name has value, or that those bidders simply don't have a clue. Usually a judgement call though.

thanks.

I am looking for expired (available to hand-reg) domains.

So deleted domains? That's even trickier, since they've been picked through a lot more. I think finding a good EMD is quite rare in the deleted lists. Lately I've been focusing more on brandables, and I find the best way to go is to focus your searches on keywords or certain letter combinations that make for attractive brandable names.

Experience, go get some

All the metrics you have listed are SEO metrics. And speaking of which, the best of them today is Ahrefs Domain Rank.

But for finding good domain names, which you could sell not to SEO'ers but to end users, all these metrics are useless. You just get the domain list and read it.
