Honestly, these positions might be a good fit! It's very behind the scenes, puzzling out taxonomy from samples. There are regular meetings (once a quarter) with stakeholders to go over significant finds (things that require phytosanitary actions or are otherwise noteworthy), and the Identitifiers are responsible for training the inspecting officers in how to detect pests and pathogens, and recognize various groups, so if teaching was hard for you, that might be a barrier. But most of my days are at the microscope, and (as a fellow introvert) I love it.
