For hunting, one of the benefit is that it is little micro-intensive way to train up marksdwarves.
And meat industry in general provides bone (mostly useful for civilian uniforms and moods) and some amount of leather. Also can provide the most food at the cost of the most micromanagement.
Fishing is less versatile but slightly simpler to set up than farming. You can either cook or process the fish, up to you which to use.
It also frequently results in deaths from fights, but it can spot ambushes that way. If you lost fisherdwarf, nothing of value was lost. You can ensure safety along with safe water supply, of course, but building a secure box is about as micro-intensive as farming.
Egg cooking is pretty similar to fishing, though requires more infrastructure at base. Though it is safe, so there's that. 1 average turkey provides enough to feed 6 dwarves for a year or so.
For plant gathering versus farming, one is over wide open fertile area, other is sealed where you need it. Farming also needs seeds, which can be gotten through plant gathering. Also, plant gathering requires absolutely no infrastructure, skills up relatively fast and is more than twice as fruitful as fishing, for instance.
Out of these, you really need plant gathering or farming for booze* - caravans can bring you booze if you request it, but that's not going to last you the year past...Iunno, 25 dwarves? Though they bring more if you forbid all your booze right before they arrive, 1 for each dwarf, which should something like bring it to 70s or so.
Though I'd consider it rather risky if you have no water.
*There's also beekeeping industry, but that takes while to scale up (9 months to split a hive) and even scaled up you only get 1 barrel per sacrificed hive per 9 months. Also is more complicated.
