I've been using what is described as "strong" for resin type. Other manufacturers will use the term flexible or ABS like. The stuff I've used can have smaller portions folded completely back in itself without breaking, while the "regular" blend will snap before reaching 45 ° deflection.
Certainly, post-processing is more involved with resin prints, but for the OP's posted requirements, the detail level is a requirement satisfied by resin printing, especially as she's had experience and exposure to the models from a vendor.
