The Smogon analysis writtenheredoesn’t recommend a physical STAB either. Fire Blast and Eruption mixed Primal Groudon is generally better.

Fire Punch doesn’t hit anything special as much as Precipice Blades+Stone Edge covers. Generally in this range are:

Out of these, only Zacian-Crowned and Necrozma-Dusk-Mane are covered up by Fire STAB. However Fire Blast generally does more damage.

Calculations

This is done by Fire Punch. Moving to Fire Blast;

212+ SpA Groudon-Primal Fire Blast vs. 252 HP / 0 SpD Prism Armor Necrozma-Dusk-Mane in Harsh Sunshine: 447-528 (112.3 - 132.6%) – guaranteed OHKO

252 Atk Groudon-Primal Fire Punch vs. 0 HP / 4 Def Zacian-Crowned in Harsh Sunshine: 420-494 (129.2 - 152%) – guaranteed OHKO

212+ SpA Groudon-Primal Fire Blast vs. 0 HP / 0 SpD Zacian-Crowned in Harsh Sunshine: 572-674 (176 - 207.3%) – guaranteed OHKO

This case both are over 100% so don’t care about it :]

As such, the best fire STAB is Fire Blast, or Eruption if you don’t mind the inconsistency of lower BP as lower HP.

Hope this helps!
