Guys, I'm back.
Still can't look at the save, but can give some opinions based on the pictures.
First, Fleme, based on one of your comments, I had the impression that you think Barnaxus has the hero promotion, which gives XP per turn. But, IIRC, he doesn't have it, so we can expect to see the golems remain with the same promotions for quite some time (according to pictures, Barnaxus has combat 2, since the golems have empower 2).
We should check which techs our enemies have in the trading screen. IMO, we have quite some time until mimics, since smelting + iron working is a lot of science, but I could be wrong. Based on score, I don't think Perp has it, though. IIRC, he tends to go culture (drama, festivals, trade), so I think we have some time.
Problem is that we are boxed between Perp and Auric, probably two of the most powerful leaders in the game, which makes chewing on the weaklings something harder.
Hunting could be a good choice of tech, since our recon line is good and hawks will be extremely helpful to scout the land and meet (and trade with, both techs and TRs, sice we have sailing) the other rivals.
We should think about trying to get a hero or some kind of collateral damage, we'll need one of those to keep conquering.
Catapults are very good in FfH, if we could trade/get construction for peace with Beeri, it could be very helpful. Although we'll need a lot of hammers to startb producing catapults...
Going Sorcery would give us potential collateral from mages (maelstrom with air mana, fireballs with fire mana, spectres with death mana...). Going AV would give ritualists with priesthood (and potentially heroes, as long as AV isn't founded yet, since someone will get them first, probably).
