I don't think anything less than an FTD 2 is going to get you any credit, but I think FTD 3 is really going to cut any time off an FFS.
A touchscreen unit is not going to qualify as the controls wouldn't work in the same way (effort required, range of movement etc). See CS-FSTD and CS-FCD. That's for EASA at any rate - I think FAA rules are more permissive but I don't have enough knowledge of that regulatory environment to expand further.
