Of course dwarves are small. The very word dwarf means small, while gnome means funny man with funny face, funny hat and funny size. Garden gnomes are small, but garden dwarves are miniscule.
THere is a word for 'little men' in all languages I suppose. Dwarf, dvärg or something else. Not 'squat men'. We follow international conventions an keep the dwarves small.
Gnomes on the other hand could be as any size as long as they appear funny

Gold is mostly training and salaries. But since it is an abstraction it could mean expensive materials that need maintenance or refueling. Perhaps the golem runs on olive oil. Then it eats supplies as well
I don't think 100 res is that much. With a nice dominion and fort you can easily get 400-500 res. 4 Golems/turn sounds pretty nasty (but I dont know how powerful you intended them).
Hinnom will have a commander that costs 123 res becaiuse of his size (6) and high res cost of magical gear.
Ashdod will have an anakite soldier with res 88.
I've tested them some. Recruitment is rather slow, but they are powerful and it feels ok.
