• Why are effects better for retries than Future?

  To try to answer the top-level question "Why are effects better for retries than Future?" I would say "because the effect types rest on a runtime that supports cancellation and error-handling with rigorous algebraic semantics." If we look at cats-retry, for example, we find implementations that require a Monad and a Sleep instance or a MonadError and a Sleep instance. The Sleep typeclass, probably unsurprisingly, just exposes a sleep effect. But look at the companion object: the only instance of the typeclass it provides is for type constructors with a cats-effect Temporal instance. IO has such an instance. Future does not, and cannot.
