DD, now 20 and at uni, plays flute and cello. She's much, much better on flute but gets more opportunities to play cello in orchestras. Flute players are very thick on the ground indeed while cellists are head-hunted.
But an orchestra would snap up a good oboe player and, as someone said, a clarinetist gets more opportunities to play jazz.
The cello is less easily transportable - watch the parental cars at orchestra drop off and you'll see that the cellists heave their instruments out of large hatchbacks while the woodwinds step lightly out of micras! (Until they're in the sixth form, then it's amazing how many kids and instruments can squeeze into a small car.)
Same when the school orchestra comes back from a tour. It takes ages to unload the big instruments from the coach. The flute players are heading home while the cellos are still being pulled out. But a flute is very easy to mislay.
A cello is a bit hard to live with when the beginner can't tune it and there's no one else in the house who can so it does need a bit more persistence at the start than the woodwind instruments.
A cello does take up a lot of room, especially in a student flat. Of the two instruments over the years the cello has demanded more maintenance. It isn't popular on a train and DD has one shoulder lower than the other from carrying hers. She loves it and wouldn't part with it for anything but the flute is an extension of her body.
Both continue to give immense pleasure!
