I mean, Larian would decide which to give freely. And just because you can't perfectly limit something doesn't mean limitations shouldn't be put in place. You can't perfectly stop people from shoplifting, but that doesn't mean stores should just let people walk out with products taken straight off the shelves.
Also your point about there being no definitive pick between which of the above choices is stronger feels like an endorsement of the suggested approach honestly. If an argument can be made for all of those, then there won't be any real harm ultimately. Players always find some kind of ideal meta in games, because they collectively spend more time with the game than the devs will, so they'll pick up on patterns and such and be able to find ways to manipulate them. That doesn't mean trying to mitigate it isn't a worthwhile endeavor.
And I would be all for more cosmetic feats that make flavor changes, but I can't imagine what those would be and do. Wild Wasteland (I did play new vegas, the only Fallout game I've played actually) was one option, not multiple.
