I would still check the pulleys.

...and to really check the pullys, in addition to spin idler and tension pully, briefly start car with belt removed, see if noise still there.

that’s a cold piston slap, it’s normal. As long as it goes away after a long drive.

I would echo whats been said, check the valve lash and accessory/idle pulleys first before chalking it up to piston slap. It very well could be some though.
