The Fuji paper currently offered in cut sheet and packaged by Harman (Ilford) is FCA Type 2 - this is not a digitally optimised paper (although it is mainly exposed digitally these days when sold in the rolls), but a regular silver halide colour negative paper, but it is the most basic, cheapest, in the FCA range the bulk of it going to cut price online digital photoprinters.
I think they choose this paper for the cut sheet because it works well for optical exposure and is available in gloss lustre and matt.
The cut sheet we used to get in Europe, packaged by Fujifilm, was the Type MP - this was a thicker heavierweight paper. When this paper was updated to Type DP, it became optimised for digital exposure and the cut sheet was dropped - I guess they thought it wasn't the best for the cut sheet which is mainly used for optical exposure. However, for anyone looking for a higher quality feel, Type DP it is fine to expose optically, but it can be a bit contrasty and needs a pre-flash.
In the middle there is Supreme - same emulsion as Type 2, but on the same heavier base as Type DP. But only available in Gloss or Lustre.
