I have used Turtlewax black" Color Magic" polish for this with good results.
I think Turtle Wax Colour Magic contains fillers, which will do a pretty good job of masking light scratches and swirls but won’t actually remove them. The main downside of a filler-enriched product is that it‘ll need to be reapplied periodically to maintain a scratch free, swirl free appearance, although IMHO it’s not too much of a hardship to do this.
I’ve never been a fan of glossy piano black plastic trim, whether it’s on the interior or exterior of the car because it is such a magnet for scratches, swirls, fingerprints and dust.
Why car manufacturers fit this unsuitable (IMHO) glossy plastic in high contact areas such as gear selector and parking brake surrounds, interior door pulls, control panels and haptic touch pads is a strange one. I can only assume it’s relatively low cost to manufacture, but in the dealership showroom the glossy appearance gives the perception of it being expensive. That shine soon wears off though - quite literally - when it gets scratched and swirled!
