I like heavy forested, completely flat 4x4 maps with a river and no aquifer. Sand if I can get it, though I rarely use it. Magma is irrelevant. I prefer cold maps for ice, but in recent versions ice seems to be broken. Terrifying if possible, but it's terribly difficult to get all of the above on a terrifying map, so most of my games end up being in untamed wilds.
I usually find a metal industry not worth the effort, either short or long term, so no anvil gives me more points than I can possibly spend. I usually invest in lots of fish and turtle for shell and bones, some pretty blue and red colored stones so I can color coordinate my workshops and doors and things, and a hundred or two logs to save time cutting trees to begin with.
Skills vary, but this is typical:
Miner/Detailer
Miner/Detailer
Carpenter/Bowyer
Mason/Architect
Wood crafter/Bone crafter
Cook/Brewer
Cook/Brewer
With no need to mine deep for metal, for the first few years I tend to build only one level at a time, and generally clean it out and make it nice before I build the next level down. So everything is detailed shortly after being mined out. This keeps architecture values high relatively early, meaning more immigrants sooner. Plus it gives my masons a headstart on clearing out untidy stone. I find that because of the inconsistency of dwarves pathfinding and hauling preferences, it's takes about three times as long to clear stone from two levels at a time as it does to clear it out from one level at a time. Twice as much space...three times as long. One level at a time makes stone much more manageable.
The wood/bone crafter is for pumping out thousands of bone and wood bolts for when I have a military.
The Cook/Brewers start out on farm duty, but get pulled off as soon as replacements arrive.
The Carpenter/Bowyer simply pumps out furniture and bows for the first year or two. I tend to have a very difficult time getting legendaries here, so I try to have as little downtime here as possible. Fortunately you don't need to be legendary to make excellent and masterpiece items, and I'm usually able to equip all my marksdwarves with at least excellent bows even with only a moderately skilled bowyer simply by making dozens of them and pawning off the bad ones on caravans.
I don't use traps, or metal, so mechanics and metal workers aren't useful.
