There is no ideal place from which a spacecraft can be launched to the Moon, I think.
The Moon is 5 degrees inclined from the ecliptic, which means sometimes above it, sometimes below it. The earth's axis is not perpendicular to the ecliptic but 23.50 from it.
Sometimes (23+5 degrees), the KSC (28 degrees) is indeed the best location. But it can also be 23-5= 18 degrees.

But for LEO, it's the equator the best place.
I've wondered : even if the final destination is somewhere near the ecliptic, can't the 0 degree launch basis be the best?
True, there would be an important course correction while doing Trans-Planetary insertion. OTOH, launching from the best location (say 23 degrees for the ecliptic) isn't the best one for LEO, so there is gain and loss but maybe one solution looses more than it gains, I don't know.
