Well first, putting it on you back distributes the weight and mass. There are ways to maximize payload without killing any and all speed.

Second, with the enhanced strength and speed, normal restrictions don't quite apply as strongly. See Nora, Ruby, and others who still move crazy fast for how much ordinance they're hauling and usually swinging. And besides, there are a few slow moving heavy hitters in canon like Coco, Yatsu, Sage, and probably more I'm forgetting.

So variety is good, and the heaviest ranged weapons can drop large threats well outside of minimum range, even though minimum range is barely a thing in Remnant. Again, see Ruby and Nora.
