The Cave
After accumulating 
25,000g, Demetrius will visit the Farm and inform the player that he would like to use the cave to set up research specimens. He'll give the option to choose between fruit bats (which leave fruit in the cave) or mushrooms. This choice is permanent and cannot be reversed.
Fruit bats
Fruit bats leave various fruit in the Cave on your farm. This is a great option for making Artisan Goods as it gives you a slow but steady supply of fruit even out of season. It also helps complete the 
Artisan Bundle in the Pantry in the first year or two, before you have enough money to buy all the necessary Fruit Trees. Fruit Tree fruit make excellent gifts for villagers because they are universal likes, readily accessible early in the game, and do not require a kitchen. Gifting may be the best late-game use for fruit, other than making Artisan Goods, Shipping them, finishing the Bundles, or eating them for extra energy (even though they don't replenish very much health).

Mushrooms
Six plots will be added to the cave where certain types of mushrooms will randomly grow. Five different types will appear, including all four that are required to craft the Life Elixir. Even though Common Mushrooms, Morels, and Chanterelles are the ones that most commonly appear, this is still the best way to craft the elixir as often as possible. This makes the Mushroom option a great one for those who love to go into The Mines, especially since most mushrooms can be hard to find otherwise. This is also a good choice for players that have grown, or plan to grow, fruit trees and do not need the extra fruit provided by the fruit bats.
Cave mushrooms can be harvested daily, but never more than once a day. The six plots begin generating them the morning after Demetrius sets them up, and again every morning after a harvest. Apparent growth time is 10 hours (needs verification), so new mushrooms will not be available until after 4 PM. Like crops, mushrooms that are ready for harvest remain unspoiled until they are harvested. If the player harvests existing mushrooms before 7 AM, there will still be no more available until 4 PM the following day. Thus, if the player goes to bed without harvesting mushrooms that are ready, one day's production is missed.
