The term FAWP was used to define the extent of the P-RNAV approval. You have approval to fly RNAV 1 (P-RNAV) up to but not past the FAWP. (These days the term FAWP has been replaced by the term FAF.)
There is no requirement for the STAR to end anywhere near the FAF. However, there are some States that publish STARs or Approach Transitions which end at the IF or FAF.
See EDDF Transition to Final Approach
As for RNAV/GPS SIDs - you can only fly them if you have GPS as a navigation sensor and are approved for Basic RNP 1 or RNAV 1 (P-RNAV)
