Unless I'm mistaken, the class of abelian groups which are local with respect to all maps $A \to B$ such that $A_{(p)} \to B_{(p)}$ is an isomorphism is precisely the $\mathbb Z_{(p)}$-modules, which makes this example look closer to the derived analog. But I believe the class of abelian groups which are local with respect to all maps $A \to B$ such that $A/p \to B/p$ is an isomorphism is just the $\mathbb Z/p$-modules, which looks further from the derived analog.
