When my group switched from DnD 5e to Pathfinder 2e, we had a new player who had never played Pathfinder before. Instead of throwing him in the deep end of a Level 5 campaign, we opted to take a break from our normal game and run a short 4 session arc.

I got to GM, and in the Cyberpunk flavored city of Sila, the group had their final battle in the Black Market. The battle map features several stalls selling everything from weapons to spell books to noodles, and a 1 inch grid that made the last fight really fun!
