:::::I think that 'picking a wire size' is one of the worst examples of when VA should be used. In a distorted current waveform, a peak may lead to an large instantaneous current draw. This may repeat for some microseconds every fiftieth or sixtieth of a second, but the current draw time-averaged over the full fiftieth or sixtieth of a second - and therefore the heating effect of the current transmission - is exactly equivalent to the actual power rating, in watts, printed on the packaging, regardless of the 'PF'. Equally, given the filtering effect of substations, transformers, and transmission lines, such spikes in the current waveform are hardly felt at all at the generating station. That is even before you account for the averaging effect of all the different appliances in use in homes and workplaces. Almost everything that has an AC to DC power supply built in - televisions, computers, printers, satellite and radio receivers, draw their current unevenly through each AC cycle, but you don't hear all this nonsense about how they're going to lead to the downfall of our distribution systems and the end of civilisation as we know it. If we're going to talk about PF and VA as relevant to CFLs in particular, then we need some very good sourcing (not WP:OR) as to why it is relevant per WP:DUE. If anyone has any, please list them here, so that we can decide on due weight in this context.
