I completely agree that accessibility/assist modes are more important and if I had to choose I’d go with that. Since we’re in a fantasy land however I’m still going to advocate for customisation because, let’s be honest, most of the difficulties (besides “the main one”) are usually not that great.

I’m speaking from a perspective of someone who tends to go for the higher difficulty options which extremely often go with the laziest possible decisions like turning enemies into damage sponge and increasing their attack power. That’s it. Stuff like improved enemy awareness, faster reaction times, smarter tactics aren’t exactly common and that’s my main pain point when selecting difficulty. There are also other things like ammo/loot scarcity, need drain in survival games etc.

Having an option to tweak at least some of these things could help folks like me who often end up in a situation when one difficulty is piss easy and the other feels like a drag. Peoples skills and expectations vary way too and there’s simply no way few basic difficulty settings will be right for everyone. And if someone damages their experience? Oh well, let people make mistakes and take responsibility for their choices. Inform them that changing this stuff will affect their experience and leave them to their decisions. We can’t (and shouldn’t) baby-proof everything, in my opinion.
