The main benefit of an electric oil pump is that you can start it before

Does it make a significant difference? It's still going to be pumping
cold oil, and for any engine that was recently run I'd expect it to have
a film of oil still clinging to any sliding surfaces.

Pre-heating everything prior to start might be kinder, but that takes
power (or, if you're a little farther north than me, lighting a fire
under the engine block isn't unheard of ;-)
