My advice: Figure out what string spacing you want/like. This is a personal preference/ergonomic thing.
Then find pickups that will accommodate that spacing, and fit into the space between the end of the neck and the bridge. Blade pickups make this a no-brainer, but as I mentioned, even pickups with polepieces typically work well for a range of spacings, despite what the polepiece locations might imply to your brain.
The 32" scale won't affect your spacing, but it will affect the relationship between string tension and string gauge and tuning. You can have the same gauge string at the same pitch with lower tension, or you can have the same tension string at the same pitch with higher gauge, or you can have the same gauge string at the same tension at a higher pitch.
