IMO, the definitive definition is 'projinfo'

spatialreference.org has not been updated in many years and should be considered out of date. I don't know what version of PROJ epsg.io is running. https://epsg.org/ runs GDAL/PROJ too, but I don't know which version, and of course that isn't going to respond to ESRI codes.

Hope this helps,
