True, but I would factor in some kind of negative to cost/longevity from increasing number of drives. Even if 16x4 is a bit cheaper than 4x16 today, will it die faster?
At these scales, I don’t think it’s measurable, if statistically significant at all.
In any case, you should always be ready to replace a drive that fails. I buy used because they’re significantly cheaper (or at least they used to be) and I’ve never had any major failures.
And while more drives means more failure opportunity, it also means when a failed drive is replaced, it’s likely of a different manufacture period.
I have a 5-drive NAS that I’ve been upgrading single drives every 6 months. This has the benefit of slowly increasing capacity while also ensuring drives are of different ages so less likely to fail simultaneously. (Now I’m waiting for prices to come back down, dammit).

I would seek the best price per terabyte while still allowing redundancy.
