Another example is the cyconium, that fascinating invention of the genus
Ficus, which is actually the entire inflorescence turned inside out. The
fruits themselves are insignificant little things on the inside which
contain the tiny seeds, if there are any.

Nitpicking time?
It is a synconium and it is turned outside in ;-)

Juniper berries sound familiar, but it is a long time since I last
looked at a juniper plant up close. Without a photo, it is hard to imagine
how a cone can look like a berry.

Junipers are found all over the world.

This should not be! Northern Hemisphere only (and mountains of Africa)

I suggest you go and look at one.
Failing that, you can find pictures on the Web. A

shows pictures of dried juniper berries & unripe ones on the plant. In the
genus Juniperus, the female cone, when fertilized, develops a fleshy
coating with one or more seeds inside. Of course it is a fruit.

Are you saying that nobody plants oak trees with the intention of
eventually harvesting acorns from them?

I have never heard of it. Acorns are not useful as food for humans,
because eating too many damages the kidneys.

+ + +
Acorns once were a staple for humans too, but they required preparation.
Gathering in the forest only. No cultivation.
+ + +

Besides, it probably takes years for an
oak tree to produce a sizeable number of acorns.
