but then, short climbs are too short to experience back pain. It happens on hard >20 min climbs - it's diffcult to keep high cadence on 1h ~8-12% climb

and yes, i can try to go slower (and also standing - which gives some relieve) on easier climbs - but this is not a point in climbs

probably my back is arching down - tight hip flexors?

I'll focus on stretching and training core muscles like all you recommended (deadlift, kettlebell swing, some other core related - like side planks with some movements etc.)

Two things can be at cause :

1) Your bike (improper fitt, size, bike geometry too aggressive for you, etc.)
2) Your body (improper position, not enough flexibility, being bent too much for too long, etc.)

If you already cleared the first one out of the list of possibilities, I'd work on your flexibility by stretching and training core muscles.

For the fact that you experience pain on hard climbs, is it a discomfort or is it pain? I don't believe it's abnormal to feel pain at some point. When climbing, your body is bent more than when you're riding on flat surface and for a longer period of time. You're struggling with your breath, you're in and out of the saddle often, you wiggle, etc. All of this can result in discomfort after such extensive effort.
