Curtailment, like negative prices, seems like something that it is hard for people to have constructive conversations about.

Probably the cheapest and best option is to build more wind and not care too much if it increases curtailment.

Yes, all the things mentioned should be looked into and done when it makes financial sense but "wasting wind" is much less a thing to worry about than "burning gas", and I'd rather waste wind than waste money.

Balancing a nationwide power grid is very complex. Some energy sources can be started and stopped instantly, but are limited - water. Others are plentiful, but unpredictable - wind. Others are predictable, but take a long time to start and stop - gas, coal(several hours), nuclear(1 day to start, fast to stop, but very expensive). A balanced grid will need all of them, will need them in quantities which can cover faults in the big producers(a nuclear reactor makes 700-800 MW). They will need them built in the right place, because while more power cables can be built, you can't transfer a lot of power on very long distances, for cost and grid stability reasons.

Nuclear power plants can vary their output faster than most people think, see

https://www.oecd-nea.org/upload/docs/application/pdf/2021-12...

   ... most of the modern light water nuclear reactors are capable (by design) 
   to operate in a load following mode, i.e. to change their power level once 
   or twice per day in the range of 100% to 50% (or even lower) of the rated   
   power, with a ramp rate of up to 5% (or even more) of rated power per minute.
One trouble is that changing the power output does put stress on components because of thermal expansion and contraction, potentially shortening their lifespan, but it something that can be designed for.

But using a nuclear power plant as a backup when there is no wind doesn't make any sense. If you build a nuclear power plant you might as well use it, costs the same either way. And if you use it, why building wind?
