Just to add to this, QGIS supports using raster images for points with data driven properties, so with some expression-fu and native tools you can get decent approximations for images from just exif data. I have wanted to build a basic template project for the solutions hub but haven't found the time yet. One issue is that qgis cannot currently distort or "warp" the raster to the relevant affine parameters, which is where the georeferencing tool may be used, perhaps using a model. Sadly, scripting the georeferencer is not that easy, however QGIS does provide a "generate gdal script" for supported transformations.
There is, however, a community plugin for doing much of this here: https://verticalphotoplacer.github.io/VerticalPhotoPlacer/ It's a bit clunky to set up and uses external dependencies like exif tools (3.22 now has a full set of exif expressions so this plugin might be updated to remove that requirement soon), but it should be functional for basic usage as I understand the original query. Just be sure to read the docs. I'm also not sure how well this would handle large files, you'd probably need to chunk your data into reasonably sized projects or individual flights etc. Just a note that this is in reference to defining and referencing "footprints" from airstations mostly, although that plugin does provide some limited visual tools like attempts at mosaicing etc. Pix4D/ AgiSoft and other commercial software is likely to give you similar results for mosaics etc from ODM and other SFM tools. If you want to orthorectify you may be better off just using MicMac directly from commandline, or if you want to georeference you can simply loop through files with gdal, ossim, or similar tools. There are also tools like https://docs.dronedb.app/ for generating image footprints etc from exif and other tools, although I had pretty limited success using that toolkit.
