I'm using imagery from OGRIP - a public aerial imagery repository (example file available here: https://gis1.oit.ohio.gov/ZIPARCHIVES_III/IMAGERY/6INGEOTIFF/_ENHANCED/WAR_2023/AS15420552.zip)

Images open fine in QGIS and are properly located. Files imported into Manifold 9 end up placed in Massachusetts, despite seemingly successfully recognizing the projection from the metadata. What am I doing wrong?

The .zip file unzips into a .tif and a .tfw "world" file and .xml. The .tif is a perfectly good, accurate geotiff that imports just fine if you remove (or rename by adding a - character to the front of their names) the .tfw and .xml files.

It's a classic case of a perfectly good GeoTIFF being messed up by sidecar files that specify something incorrectly. See the "Projections from Accessory Files" section of the Projections topic in https://manifold.net/doc/mfd9/index.htm#projections.htm for how what's in sidecar files will override the projection info, if any, specified within the main file.
