OP thought his range was draws/made hands turned into bluffs but then wasn't sure if he should call river. If he's not sure he should call river here then that means he expected his opponent to mostly stop bluffing on the river. If that was his assumption, he should have shoved turn given the range he put him on.
The description he gave on villain was kinda vague so it's hard for me to have a read on his range. OP had an idea about his range so I base my analysis on that. If you wan't to be unexploitable here you have to know your own range and call with the top x% resulting in villains bluffs being 0 EV. Unexploitable means no exploiting from our side though and given the range OP put him on and the assumptions about his play he definitely seemed to have an opportunity to exploit by shoving turn.
If our assumption is that villain doesn't bluff the river often then I think we are exploiting him by calling. We can then play the river perfectly.
I don't feel like we are really exploiting the villain by shoving the turn even if his range are mostly draws and things turned into a bluff. Villain can't have many combo draws since we got the J 
so his draws got around 20% equity. Shoving villain off 20% equity while getting it in with 5% equity vs villain's value range doesn't sound like exploiting him. We obv got a profitable shove if villain calls with a portion of his drawing range.
The balanced approach for this spot is standard when we don't know how to exploit the villain because we can't estimate his bluffing frequency or how he constructs his river range.
