Unfortunately we still need tunable baseline power in order to keep current, voltage, and frequency within the grid’s margin of error. Our options for that are: situationally available (and often environmentally problematic) hydro, fossil fuels, nuclear, and/or giant toxic/fire-prone battery banks.

Out of those you listed, nuclear is the least flexible in terms of output regulation. PV with batteries is the most flexible.
Hydro is definitely the least flexible. Those gate move slow.
Hydro is often turned on and off as pumped storage. Nuclear never is
Running frequency regulation off batteries is a silly idea, that’s more capacitor range. Also, flywheels, which is how fossil fuels do it anyway.
