I noticed after creating an unstructured mesh that the layer definitions for confined/unconfined are no longer available. How does FEFLOW treat this now that the layer options are gone? Is the model forced to be fully confined? If so, does that mean that the model can no longer go dry and that negative pressure heads would be the only way of estimating where the model would have gone dry if it were unconfined? Is the only way to model unconfined conditions to use the variably saturated approach?

Yes, that's correct. You need to impose confined conditions or solving for Richards (unsaturated flow) if you use partially or fully-unstructured meshes.
