Does the term 'cartridge bearing' mean it is sealed to keep contaminates out and factory installed lube in? Or does this nomenclature mean something quite different?

I haven't tried treating the squeak with oil because I thought it would be useless. Should I give 'er a shot and see if it helps?
Most bike components using "sealed" or "cartridge" bearings use standard commercial bearings with single lip seals. These seals are intended for indoor use such as on electric motors and not, despite the marketing, weather sealed.

A proper weather seal requires a double lip seal with a gap between the seals so water cannot migrate in. Read more about seals here.

Odds are that after some use in weather water got into the bearing, and washed out or compromised the grease. If you open them odds are up you'll find brownish grease or stains, and it isn't food coloring.

Depending on the specific design and your skill level, some of these can be serviced, and others not.
