After I learned some rules of the class, since my swashbuckler has small Con, I will choose Rogue-like Archetype (Pimpernel) as she reach lvl 3 later.

Matador fits better for a tank with high Con. Dread Pirate is great for debuffs, but doesn't really fit with my narratives. Musketeer and Trickster don't fit with the setting.

TLDR: my swashbuckler can detect and may disable trap at level 3; and we still need a tank
