In Indesign CS5 I could set fitting options on a template, have an image place into the centre of a picture box at 100%. In this case a barcode for example.
In Indesign CC it defaults to top left every time.
Its a small thing but a repetitive thing all the same!
I have a further observation / development with regards to your start-up script.
With the script in place the action of placing an image into a box with remembered fitting options works perfectly but...
When I use the links palete to re-link a logo the new linked logo is placed top left and not in the same location as the logo its replacing.
Is this something you can address and amend your script?
