Further clarifications:

1. Before doing anything with the images, I want to know a little about
their distribution with respect to fileformat, pixelsize, color space,
bit depth, RGB or grayscale and perhaps PPI.

what for? what will you gain by knowing this?

2. I have investigated some twentyfive pseudorandomly chosen images and
found a mixture of JPEG, TIFF, NEF and ORF formats. Among the JPEG and
TIFF images, both sRGB and Adobe RGB is present as well as one ProPhoto
RGB (presumably created by a scanner). Four of the viewed images are
grayscale - likely scanned from B/W negs.

what matters is what the photos are *of*, such as which people are in
the photos and where and when they were taken, not whether the file is
a jpeg or nef.

nevertheless, import all of them into lightroom and organize as you
want, whether it's by subject or file size/type.

I thought that having data regarding the images imported to MS Excel (or
some other spreadsheet-SW) could allow me to get some 'overview' of the
'physical' contents of the imagefiles.

excel is the worst possible choice.
