The OP literally lays out a way in which God could have created benevolently. This line if attack by reversal does not work.
You said in your OP:
"This is a form of special pleading: normally when we see someone allowing suffering, we conclude that they're malevolent or at least criminally negligent. But in the case is God, a special case is made appealing to the fact that God is powerful and knowledgeable; so we can't conclude that God allowing the suffering is malevolent."
Your argument falls flat on its face because it is patently illogical. What you have is a logical fallacy whenever you compare God with a human and expect God to do what a human would do because God is not equivalent to a human. God is not Superman who comes swooping down to save everyone nor does God have any such obligation. To expect God to do that is special pleading
special pleading: argument in which the speaker deliberately ignores aspects that are unfavorable to their point of view.

Not only that, your argument assumes that there is no reason for suffering, and that all suffering is bad.
False equivalence is a
logical fallacy in which an equivalence is drawn between two subjects based on flawed or false reasoning. This fallacy is categorized as a fallacy of inconsistency.
[1] A colloquial expression of false equivalency is "comparing apples and oranges".
Characteristics
This fallacy is committed when one shared trait between two subjects is assumed to show
equivalence, especially in
order of magnitude, when equivalence is not necessarily the logical result.
[2] False equivalence is a common result when an anecdotal similarity is pointed out as equal, but the claim of equivalence doesn't bear scrutiny because the similarity is based on oversimplification or ignorance of additional factors. The pattern of the fallacy is often as such: "If A is the set of c and d, and B is the set of d and e, then since they both contain d, A and B are equal". d is not required to exist in both sets; only a passing similarity is required to cause this fallacy to be used.
False equivalence arguments are often used in journalism
[3][4] and in politics, where flaws of one politician may be compared to flaws of a wholly different nature of another.
