Would it be 60 miles for 1° in all locations for the latitude, considering that the earth is an ellipsoid/spheroid?

Latitude is measured along a Great Circle of Longitude - confusing isn't it? So the distance between (say) 10 and 30 degrees North is the same as the distance between 50 and 70 degrees North.
The Latitude circles (in the 'horizontal' plane) get smaller as you go from Equator to the Poles, but all the Longitude Circles (in the 'vertical' plane') are all Great Circles and go through both the North and South Poles and so are all (pretty much) equal in size.
