I would also say a lot of classic D&D fantasy settings would support a bunch of Arab pirate stuff.
Greyhawk has the western third of the main continent dominated by the fantasy Arab Baklunish, though the west coast would be limited to various Baklunish nations for pirating as the Sea of Dust cuts them off from sailing to the rest of the setting.
Forgotten Realms has not only Al Qadim/Zahkaria, but the separate fantasy Arab core nation states like Calimshan/Amn etc. The Anarauch desert has bedouin style nomads but not really a lot of Sinbad pirate style opportunities.
Birthright has a big ethnic fantasy Arab North African Khinasi set as a big part of the setting supported with supplements like
Cities of the Sun.
Golarion from Paizo for 3.5, Pathfinder 1e, and Pathfinder 2e has a whole continent of a super fantasy Arab empire and a couple core fantasy Arab nations along coasts plus there is a whole 3.5 adventure path based on a genie theme set there.
