Ideally, I think you’d want to use hydro and geothermal first, because they are local resources that can be built with relatively low overhead, and where you can’t, just spam nuclear (assuming it is within the country’s capabilities), with a massive storage-infrastructure-stabilized (preferentially offshore) wind and solar kickstart. Classical renewables have the advantage that you can build up capacity efficiently, and we are definitely on a timer here.

However, the real world is a little bit more complicated, so I think really we should just take what we can and not overthink it too much. Functionally, there’s no single, clean, silver bullet energy source.
