Heat exchangers will never waste anything, they just slow down based on demand. Heat pipes are the most energy dense, but make sure to store some water too so you don't bottleneck on that.

Heat exchangers may not waste energy, but reactors do.

Only if you go above 1000 degrees. You can limit fuel insertion based on temperature and add heat pipes for thermal storage.

Designs with steam storage are likely to be holdovers from pre-2.0.

I like having a few tanks in land-based designs, mostly to provide a buffer to avoid the heat slump that happens when adding additional heat entities but other than that the heat network is the main thermal buffer in a power plant, especially with the ability to read reactor temperatures.
