aside from their polarity, why are these compounds insoluble in ether yet soluble in water? And if citric acid is soluble in water, why is benzoic acid insoluble in it?

Their polarity IS the reason. Like dissolves like.
And by the way benzoic acid is not insoluble in water.

Polarity is the answer. Benzoic acid is insoluble in water because of the non-polar benzene ring connected to the carboxylic acid crew. Glucose (many hydroxyl communities), glycine (small and actually polar), and urea (also small and actually polar) do not have adequate non-polar structures to stay away from solubility in water.

Ether is not a polar solvent, and does not form hydrogen bnods in solution.
Water is polar, and does form hydrogen-bonds in solution.
So:
Like dissolves like.
Glucose forms hydrogen bonds.
Glycine is polar.
