Hezbollah members include medical personnel, teachers, politicians and so on. It is a much larger group of organisations than the armed factions.
I'm not sure what you're after. What the israelis did would have been a worse crime if it actually was targeted. Is that your point?
It's not clear that Israel just set off all Hezbollah issued beepers; we don't know what methodology they used. We can guess based on reported casualties, but we don't know which casualties were involved with Hezbollah's military operations.

It was certainly targeted, it just also had collateral damage, i.e. harm to non-targets.
What you have Israel do instead? Suppose they struck Hezbollah fighters with conventional artillery. They're not sitting around in open fields, so there still would have been collateral damage.
Would you again maintain that the strikes were "untargeted" because there was collateral damage? By this unusual definition, it seems impossible to do a "targeted" strike at least in any urban environment.
