For episodes where Riker would need to consult the holodeck, rather than just one of the other main characters, in order to come up with some sort of a serious decision, the list is short indeed. The episode would have to feature either
a) Riker physically cut off from the other heroes or
b) Riker emotionally cut off from the other heroes
and in the former case (say, "Gambit"), he probably wouldn't have access to a holodeck! Perhaps Thomas Riker, stranded on that planet for all those years, might have used a local holodeck for soul-searching, possibly finding consolation in what happened to the ENT heroes in the "TATV" story or some other ENT story the writers could have come up with. But that wouldn't have been much of a connect to TNG, considering how peripheral Tom Riker was to the show.
So we need an emotional or ethical disconnect. What do we have? Siding with Worf in one of the Klingon's criminal endeavors of vengeance (say, "Reunion" or "Birthright")? But Riker never took an active part or made a decision in such episodes, that we would know of.
Pondering whether to bail out Wesley in "The First Duty"? But he didn't, and the story of him deciding not to would be a bit silly. Even more so when considering the episode was all about Wesley making the big decisions.
Pondering whether to bail out Wesley in "Justice", then? Too bad that he was basically stranded down on the planet most of the time...
But Riker in the early seasons was a more active decider than later on, so perhaps we indeed should target that group, despite it being patently impossible for Frakes to look that young. Yet what judgement call of his would not have been lighting-fast but could have involved prevaricating on a holodeck? The only episode that took any appreciable length of time was "Pen Pals", and again we could at best have Riker decide that he will not expose Data's illegal communications and will act surprised when those are revealed.
And Riker's decision in "The Icarus Factor" did not feature an emotional or ethical disconnect; if anything, it was an episode the least likely to see Riker shun contact with his (admittedly mostly barely year-old!) friends and instead trust a holographic Archer to sort out things for him.
Also, "The Pegasus" really is the only time we catch Riker doing something seriously wrong and then coming off clean. All the other times he changes his mind, it's over something less significant, say, a romantic liaison - or something fantastically more significant, say, choosing not to become Q.
Of course, as pointed out, using "The Pegasus" just plain doesn't work, due to the time concerns and the fact that the decision was explicitly made differently. But hey, they could have made the episode about the Pegasus instead! That is, an all-new story where Riker tries to resolve his feelings about the old incident, before the events of the episode, and again after it, rather than during it.
