An argument / possible explanation that I've heard is that the increased risk for suicide can be attributed to the beneficial effect of reducing lethargy and fatigue, effectively removing one major barrier between suicidal ideation and carrying out the act.

That is a possible explanation, but it does not explain why the effect is so pronounced in younger people and goes away with age. The truth is we just do not know how the popular antidepressants work to begin with and we sure as well don't know what makes them create suicidal thoughts. It is best to gather and publicize available evidence as best as possible and thread carefully.
