I'm a little late to the party... I originally wrote the following script for a user at the Adobe User Forums, it will pair alphabetically sorted files from an image folder with images from a mask folder, converting the background image to a layer and applying the mask image as a layer mask to the image, then save out a PSD. If it is not 100% of what you are looking for, it should be "easy enough" to modify.
[CODE=javascript]/*
Combine Image & Mask Images to PSD.jsx
by Stephen Marsh - 2020
//community.adobe.com/t5/photoshop/automated-layer-mask-from-separate-silhouette-file/td-p/10865377
Code based on the following topic thread:
//community.adobe.com/t5/photoshop/batch-process-groups-of-files-based-on-numbering/td-p/10809093
NOTE:
There is no error checking, the 2 input folders must all contain the same quantity of alphabetically sorting images.
No Files should be open.
It is assumed that all files are RGB.
It is assumed that all files are flattened with only a "Background" image layer.
It is assumed that all files will be saved with a single masked layer, named after the document name.
It is also assumed that the old and mask files all have the same width/height/resolution.
Original file names will have a prefix of "Masked_" added.
