I know it´s the same point as my previous point; but even with map finder, I don´t seem to be getting starts this good.
Which Map type are you using?
A start with two commerce and two food resources shouldn't be too hard to find with map finder. Try searching for just one commerce tile; I think it will exclude plantation resources which are useless for an early research boost. Otherwise, just search for either Gems, Gold, Silver or Fur. These are all the Commerce resources that require early Technologies (either Mining or Hunting) to improve.
Two commerce and two food resources are more likely with some map types and less likely with others.
Great Plains may provide such a start; The east side of this map has forested grasslands which is a good place to build cottages. The forests can be used to chop the first part of a Cathedral and Slavery can easily do the rest, especially if you have the Cathedral's production multiplying resource. Great Plains also seems to have plenty of Marble, if I recall correctly.
I've looked at all 18 BTS HOF (12 of them are available in Warlords and maybe Vanilla too) approved Map types for this gauntlet, but they all have drawbacks. Although Inland Sea has the best dates so far, I think it is only because the best players are using it almost exclusively. Other Map types may be better.
Any Map type that doesn't have a single land mass where all Civs start should not considered seriously, since that would severely restrict trade, even to nothing if you are on your own continent with no access to others Civs until Astronomy is researched, tall ships built and new lands (Civs) discovered.
Whether in the Capital Big Cross or 3-6 tiles away, you also want to find at least Marble. Copper and Stone (within a 6 tile radius) would be good to find too. Some Map types have twice as much Marble, Stone or Copper than others. This may have more of an impact than having only 1 Commerce or 1 Food resource in the Capital site. Some Map types have 2-3 times as many Marble, Stone and Copper resources as others. Highlands for example seems to have plenty of all three of these strategic resources.
If you choose option "Choose Religions", you can pick the Religion of any Technology that provides a Religion from a list of those yet to be found. Obviously, you should pick a Religion matching the production multiplying resource you have. This means you might be able to research Theology and found Islam which has Marble as its "Cathedral" production multiplying resource.
The most important consideration for Map type may be the need for grassland s and floodplains on which to spam Cottages in the two Cottage cities and spam Farms on the main (Culture) GP Farm and and any secondary GP Farms.
More riversides for the Cottages is a secondary consideration for Map type choice as well.
