BLubmuz, if we settle desert, we would possibly delay bronze working after wheel-pottery (even writing?), there is no forest in BFC, so early whipping is not possible.
You also wrote that settling on marble is losing 4H3C tile - but it is not. It is converting it into 2F3H1. Riverside plainhill mine is only 2commerce less and it is not a big deal with gold in BFC. More hammers on the other side IS a big deal.
Looking at the screenshot we already have in the fog I suppose:
anticlockwise direction from mountain range: mountain, plainhill, riverside grass, riverside grass, riverside grass and at least 2 forests and 3 unrevealed tiles. It sounds really good for me for beaurocapital if we irrigate the only one floodplains (that gived us +8 food, that is growth every 3-4 turns. enough for early whipping). Having so many riverside grass we can irrigate one more and have some chance to get more resources there.
Greatplains mapscript is also poor with health resources and unless we get any from trade, 5 FP in BFC will be a unhealthiness problem changing cottaged FP practically into cottaged grassland.
Not being forced to go straight to pottery means also earlier settler and a second city with copper.
I am also still wondering, why mapmaker put a quarry if we already know masonry and are able to spawn worker early...
No time for test game yet
Anyway, settling "empty" PH is no option for me = too many unworkable tiles and a possibility to block anther nice floodplain city.
EDIT
We also know pottery, that means also quicker granaries and regrowth every 2-3 turns. It also determines delaying the wheel AFTER BW
