I think, @xzczd, that the way to answer that would involve the IntegrationMonitor framework that Anton introduced to us previously. Which would be an interesting separate question, I would say.

@J.M. I should say I'm a little surprising, I didn't notice that NIntegrate evaluates its first argument while it owns HoldAll attribute, well, does NIntegrate always evaluate its first argument? (Maybe I should start a new question?) BTW @anton the // Expand is redundant :)

As an addendum: "SymbolicProcessing" -> 0 does absolutely nothing because BesselJ[] is already auto-expanded in the half-integer case, and the resulting expression is numerically iffy.
