There really isn't much of a difference between doing 6 reps vs 12 reps, what matters is going to failure which I think may end up being harder when doing 12 reps because people maybe don't realize how much they have left in the tank.
Going to failure can also be a question of which ‘link in the chain’ is hitting failure at any given rep range.
Bent over rows being and easy example: at a 5RM upper back is giving out as desired, but past 10RM my lower back is the issue. If my goals are bent over endurance in my core then higher reps will force adaptations where I’m weak, if I’m trying to get my shoulder blades sexy and humpy I gotta keep the stimulus where I want results. In addition to manipulating reps something like a snatch grip can provide a leverage based answer to the same targeting needs.
Proximity to failure is key, targeting and maximizing that proximity is individual and highly goal dependant.
[As a bit of a physio case I’ve found General Gainz (/r/gzcl on Reddit), to be a highly productive RPE based system with very happy adaptive approach to hitting personal limitations mid workout; no “failures” or broken spreadsheets = motivation = consistency = progress; strong recommend to check out]
