It looks like, based on my reading, the image mosaic, unlike the pyramid layer is not as good at serving large overviews, as everything is partitioned into many tiles, but it is very good for serving the detailed data itself and large volumes of it. Is this a correct assessment?

As far as volume, we're talking about the 150GB-800GB range, depending on the dataset.

First discriminant, you want to to show the data at all scales or just at the small scales ? Second discriminant, how much data are we talking about? Order of terabytes or order of (tenth of) gigabytes? Generally speaking I tend to avoid using a pyramid (files base or db based) and thend to prefere a mosaic; anyway it would be great a bit more about your use case.

Is there any known ceiling to 1) number of images 2) total size and extent of images for either method?
