I was bored on Friday and the sun was out and there wasn't a cloud in the sky, so I took my Eye One outside and measured the light. It is almost a perfect match to D65 light. Is there any benefit to either using my measured light source or D65 for all my outdoor prints, which is 90% of my work? Would it improve the perception of colors matching?

Daylight can actually vary in temperature from 5000k to 6500k. 6500k is the expected reading for a overcast sky or northlight. 5500k is the generally accepted value for true daylight. I think it would be much safer to standardize on 5500k for your outdoor work.
