Success!
New front O2 sensor improved the situation a lot!
But occasionally I get this hesitation, so it's not solved entirely yet. Perhaps it would happen 4 times out of 5 before, now it is once out of 5 and much smoother / gentler.

Could the rear O2 sensor bring more improvement / solve it entirely?

I didn't disconnect the battery after replacing front O2 sensor. I did it now and I'll report back if there's any change.

PS.: Previously I unplugged the battery a few times - there was no change then.
