Tested on Adobe InDesign 19.0.1 on macOS Ventura

Steps:

I save an image on PS as JPEG and preserve the metadata
I place that image on InDesign.
The file info panel is showing the metadata
I configure and generate the caption with the ISO speed
The caption do not show any info about the ISO speed

When working with psd or pdf it works fine. When working with JPEG not created from PS or Lightroom works fine.

I attached an example and screenshots the jpeg
