So I say to you, @femcube, once and for all. The Chorus Fruit of Minecraft is a vegetable.

I say to you; In order for chorus fruit to be a vegetable it needs to be a plant, is it a plant? We may never know, let's just say it is. Since chorus plants are plants, chorus fruits have to be a vegetable, for they an edible part of a plant. All fruits are vegetables. Thank you.

Addressing your accusation that Chorus Fruit aren't fruit; First off the flower being the only useable thing to grow a new chorus tree isn't sufficient evidence against the claim that they are. Trees in minecraft aren't grown from their fruit and seeds, only saplings from their leaves. Cacti and Sugar Cane we just take a piece off to replant, and not their seeds. It's a common trope in minecraft to skip seed planting for large plants.

Now most ornamental flowers I know of have a blooming and dying phase where after they die the petals usually fall off but sometimes stay and we're left with a fruit, everything that flowers has a fruit unless it's an exception like the cherry blossom which is a cherry tree that doesn't produce a fruit, it relies solely on other ways to have more of itself in spite of it being a prunus.

Additionally you've yet to explain what the chorus fruit are. Let me note that each stem block has a bulbous appearance and drops 0-1 chorus fruit. Meaning it's inside, since we don't see the fruit on the outside, but why is there a bulb you can easily detatch inside? It makes no sense. Also mojang has officially stated endermen love to the eat the fruit, which when eaten teleports the consumer and I assume is what gave the endermen the ability to teleport. This explains why the plants are across the various islands, the fruit, when eaten, teleports the consumer, allowing the fruit seeds to be elsewhere to spread more. Fruits in real life do this, they let themselves be eaten, in order to spread their seeds. Now why is the fruit inside the stem? As I've stated before to protect it from the harsh natural elements, the endstone is bleached, there's natural light everywhere, it makes sense the outside is harsh.

Now interestingly a mojang article mentioned the end is in constant twilight and that's when dragon fruit bloom, in order to attract moths and bats for pollination. This implies there might be moths in the end that pollinate chorus fruit, which since the end seemingly has no wind that we know of makes this how we can explain how chorus are pollinated, tiny moths the player can't see, though there is no way to confirm this yet.

Now you mention chorus plants grow more limbs to spread better, possible but I'm having a hard time buying it when they rely on being eaten and the distant between trees in the end does not imply your stance. Chorus have been compared to cacti by monjang and those cactus that grow more arms usually do it to store more water. So storing more nutrients is certainly possible but with seemingly no weather in the end it seems unlikely. However it may just be due to the plant producing more flowers as it grows taller to attract more pollination and make more fruits. The plant is always in bloom, the flower grows the stem from underneath it, making my theory that it grows a fruit inside the stem as the stem grows around it pushing the flowers away once it's ready to start growing the fruit inside more plausible. The flowers are notably flat against the plant and we cannot tell just how deep the ovaries are but they could be at the center only reachable by a tiny moth. The reason some stem blocks might not drop a fruit is because the flower failed to be pollinated before it grew its stem again and/or the fruit got damaged during harvest. It is to be noted the flower block is bigger than the stem, which supports the stem growing from under it pushing it away, making its noticeable chorus sound when it does this, as I doubt something with such a stiff looking structure would shrink, but if it does shrink that'd be around the fruit it's producing making the bulbous shape. I will concede there's very fruit that grow inside the plant, but there's at least 1, figs, though the reason the fruit is inside is different from why I stated chorus does it, it still gives precedent for such a thing/

As we've gone over, there's nothing exactly like this plant in real life so I must use what information I have about how fruit in real life work and the similarities and how that could apply to the chorus plant.

So I say to you, @femcube, once and for all. The Chorus Fruit of Minecraft is a vegetable.
