I can't think of a reason for a crafter to be a gargoyle, if not an imbuer.
To get the most skill points out of a carpenter, it would need to be Elven (to allow the use of the Song woven mantle, to save 10 skill points). An elven carpenter can make musical instruments by getting all 45 points in music from craftable equipment and a talisman; humans require the same (minus the mantle) plus 5 real points, or the Bard version of the Mark of Travesty.
To be a tailor and/or smith, one is best human for the heavier carrying capacity without being overweight (important for crafting, as well as turning in BODs and hauling the rewards back home).
Gargoyles can't use mining gloves, and 101.1 or higher mining is ESSENTIAL for maximum ingot return from recycling crafted smith items. After all, ingots are a lot harder to get than residue and essence, which is all you'd get from unraveling failures instead of smelting them back to reuse.
Gargoyles shouldn't even have the option of having the Bowcrafting skill, and again the weight allowance of a human is more useful for doing quest runs trying to get runic fletching tools from Heartwood.
