The problem with appealing to episode details is that the transporter is presented very differently in different episodes depending on the needs of the story. That's fine for storytelling, but it means we can't pin down a fixed set of rules for how transporters work. To ponder philosophical questions we have to invent rules by picking and choosing presentations of the transporter that seem most interesting, and filling in gaps with our imaginations.
Yes, there's the episode where Barclay is conscious during transport. But there are contradictory presentations where Scotty puts himself in stasis in the ship that crashed on the Dyson's sphere, and M'Benga putting his daughter in stasis. In those cases neither has memories of time during transport.
There is the episode where Picard uses the transporter to convert himself into an energy being to try to live in a space cloud. The story is the transporter converts matter to energy, and energy in Star Trek is another possible state of living existence. Thus continuity. But there is a contradictory episode of DS9 where crew members' physical and neural patterns have to be stored in computer memory, not "pure energy", and we see holosuite character versions of them.
So there's either no suicide booth problem, or there is. You get to pick depending on which scenario you feel like talking about.
