I would caution against the .eu exoplanet catalog. It seems to be poorly maintained and contains many errors in references as well as in units and data given.

Most data that we call 'composition' is the mean density interpreted on some equi-density line. There is no unique composition that we know of for most non-gas giants, so if you want scientific scrutiny, then unfortunately there are no answers yet for all those classes of exoplanets.

Where can I find datasets for all confirmed exoplanets, terrestrial exoplanets, and Super-Earth exoplanets?

The NASA Exoplanet Archive has a [Planetary Systems dataset](https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PS&constraint=default_flag%20%3E0) offers celestial mechanical data for 5,197 confirmed exoplanets. The [Exoplanets Catalog](https://exoplanets.nasa.gov/discovery/exoplanet-catalog/) classifies these exoplanets as terrestrial, super-earth, Neptune-like, or gas giant. Where can I find spectroscopic data, estimates of composition, and/or data on water (or rock) for these exoplanets?
