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.
Would geothermal work? I can’t think of any particular reason that the heat of the earth should vary much with time (feel free to correct me if I’m wrong in this assumption), and energy production should be more controllable because to my understanding it generally just makes steam for a turbine like more traditional power sources.
You forgot hydrogen, saltwater batteries, proper grids, biogas, etc.
If you’d use nuclear power like that, you’d drive up the costs even more, because it’s just not very viable to compete with solar and wind during the day. Better to just invest in proper storage solutions.

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.
