Hey, so to answer this quickly, you can make profit with any craft there is, some are harder or take longer or even need more up front capital for it but it's possible to make a good profit with every single craft in the game.
Now to go into a bit more depth for you, we can break the crafts down into three basic subjets, Big Items, NPC'able and Consumables. Big items would be things like Armor, Weapons, Items that a player can buy that have a good use. Comsumables would be things like Ammo, Food, items that get used up that you need to buy over and over. NPC'able are items that you can craft then sell to an NPC and make a profit.
Big Item crafts would include, Smithing, Goldsmithing, Woodworking, Clothcraft, Leathercraft, Bonecraft and to a lesser extent Alchmey it has a few weapons and things.
Consumable crafts would include, Cooking, Alchmey and Woodworking(Ammo)
NPC'able would include every craft, as I've leveled crafts up I've always found at least 1 craft I can sell to an NPC for a profit even if it's been 1 gil.
Now I'm not going to tell you which craft to level up, each has it's pro's and con's and each will take differnt ammounts of starting gil to get going. What I am going to do is provide you 3 links. http://www.ffxiah.com/ http://wiki.ffxiclopedia.org/wiki/Crafts http://www.ffrecipe.com/search.php
You can use these links to do your research into what craft is for you.
I hope this helps.
