Easy one here.

Put closed cell foam (aka blue board) on top of lid and underneath. Most often the back of the freezer does not have condenser coils under the metal outside "skin". You can literally feel the heat on the metal skin exterior. Insulate on non condensed surfaces.

Choose your rate of return. I used 3/4 inch closed cell foam (R6) on my freezers (top, bottom and back) and it dropped kW hr consumption by almost half.

Glued it on with spots of liquid nail every foot or so. Purposefully left a 1/8th inch air gap. Sealed the edges with metal foil tape.

As a 'fridge, I bet you get even better return.
