Both the iron wall lamps (wall mounted furniture in general) and stacked foreign fruit are good gifts for villagers.
The advantage of iron wall lamps is they increase friendship faster than the fruit stacks.
The disadvantage of iron wall lamps will eventually cause the villager to remove their original wall/homewares furniture. Villagers have an inventory limit of 64.

That being said, if you don't care about keeping your villagers "original", then go ham on the iron wall lamps.
