I know that the fruit trade doesn't look very useful. I do agree that since it also uses magic fruit, it kinda duplicates what the glimmerbulb trade does. I have used this trade because I tend to accumulate mushrooms and truffles without even trying, so I did have max of these for a while. The crop trade needs 60 strawberries and I don't usually have spare strawberries lying around, so I do grow them specifically for that trade.
So all in all I'm saying, the trade is slightly useful, but not very. You're not missing out on much, but if you don't have anything else to do, you might as well. So yeah, I'd agree with ignoring it for a while.
