If everything is constant would I jump higher when the sun is above me or at night when the sun is below me but farther away?

Think to the tidal pattern and the location of the moon.  You'd jump higher at noon and at midnight than at dawn/dusk.  In theory the gradient of the gravity is larger when you're closer to the sun, so noon would be ever so slightly higher than midnight, but this would be negligible compared to noon/midnight vs dawn/dusk.

Note that the moon has roughly twice the tidal effect of the sun however.
