F-35 cannot carry any standoff weapons inside its MWBs exept for probably JSOW, but JSOW is a stand-off weapon for technically retarded enemies only.
Our friend
@asianobserve ran out of real arguments when he needed to use videos of air shows to prove a point, or justifying the lack of performance by saying, there is no "significant" TWR advantage, which still means that there is an advantage. So we can stop talking about flight performance since there is no basis for the F35 to begin with.
On the stand off weapon capability though, you have to distinguish between difference of tactics for stealth aircrafts and non stealth once!
The advantage of stealth is to close in to a target without being detected, while modern non stealth aircrafts try to avoid closing in, by using weapons from longer ranges. So for an F35 using a 2000lb JDAM against a high value target at close distance, is more effective than using a cruise missile like Rafale would do from long distance. Same goes for A2A combats as well, where non stealth fighters try to increase the distance for BVR shots, by long range visual ID (FSO-IT), or the large no escape zone advantage of Meteor to their advantage. A stealth fighter on the other side can close in and would benefit more, from short to medium shots to increase kill probability. That's why the US is considering smaller missiles, that are more suitable for stealth fighter tactics and load restrictions.
