Off the top of my head, some notable things I've found useful in army demographics posturing:
-Volunteer army (6 foreign legion) upgrade for 70 gold each to 70 strength infantry at plastics. In a peaceful game you are often beelining plastics anyway, so this is a match made in heaven.
-Gatling gun upgrades, though of dubious worth in war relative to crossbow, is a huge swing in demographics.
-Early game, hold back on Metal Casting, and hammer out warriors, upgrading them to iron swordsmen for 80 gold. Composites are better for the national defense and the actual fighting, but swords in the demographics might convince the warmonger to hit your neighbor instead.
-Frigates, in addition to being extremely useful ranged units, also have a large combat strength score.
The ottoman's UA often gives them a ton of combat strength in garbage stolen ships. All 20 caravels might 1 shot themselves colliding into city walls but it sure does look impressive!
For similar reasons, Shaka (tons of promotions and half Melee maintenance), Bismarck of Germany (25% land unit maintenance), and Catherine of Russia (tons of spare horse & iron beyond what you can trade for your own forces)
