Ok, so I started playing. I decided to allow us only one scout, with a restriction to not use it for attacks (even if upgraded in a ruin). Hopefully no one founds this solution to be too bad; I was really torn about what to do, but I didn't want to delay playing the save any further. I tried to find a compromise between fun and variant and that's what I ended up with.
Anyway, on to the game.

I've settled our Capital of faith on the Marble, which gave us the 15% wonder boost. I renamed the Capital to Faith, but we should probably choose a better name for it. Started on the scout we are allowed to build, research on pottery -> trapping, plan is to go scout -> monument -> granary -> worker.

We soon found a ruin, which gave the +1 pop result. This reveals how food poor our Capital is, forcing us to work a 1/1/2 tile. Not great, but what can you do?

We met Monaco, which is pretty close and appears to be in a peninsula of some sorts... I don't think we'll have any opponents near it, so I pledge to protect it already, for the +5 influence. It's a cultural CS, so no free units for now. You didn't think it would be that easy, right?
Finally, the reason why I'm reporting so soon: we got enough faith for a Pantheon and I think that's an important enough decision to stop for a bit. Here's the revealed terrain:

There's nothing revealed so far that points towards a specific faith-generating pantheon... There's non-forested tundra, but I don't see us working such poor tiles only for faith purposes. My initial thought was to get the Goddess of the Hunt pantheon, which gives +1 food from Camps; that'd probably help with our very low food Capital (+3 food from what we can see so far, enabled pretty early). Not game breaking, but useful, at least.
For a thematic choice, there's God of War, which gives faith for units killed near our cities. Ithink we get faith even while killing units by bombardment, so that could add up when the barb invasions arrive.
So, any opinions? After thinking about it, I'd probably go with God of War. It's probably the best faith generating option we have + it's fun. With no clear best option in sight, I guess that's good enough.
