No and no. There just aren’t enough of them to be informative, overall. The NT is much denser with cross-references than the OT. If you want a reasonable number of cross-references in the NT and don’t care much about having them in the OT, save for a few key areas like Isaiah 53, then you’ll be fine.
If you are interested in footnotes, without question get a different version.
More footnotes, however, will compromise how well the bible holds, etc. As it is, the maroon paper one I have handles well. So if you just want to read it, sitting in a armchair, it is good. It has sufficient headers to aid in finding passages and the pages are clean/pleasant. It seems designed for armchair use.
