Ore guide — all 7 ores plus the biome liquids, and what's worth keeping

Quick reference, since this isn't written down anywhere yet: the seven ores are Iron, Silver, Copper, Shadow Metal, Gold, Aetherium and Valorium. Ore only starts dropping from level 3+ NPCs, so low-level farming won't feed a crafting habit. On top of the ores there are five liquids: Aetherspring and the rare Solmead in the normal biome, Pyrebrine in the hot biome, Voidbrine and Mirefen in the cold. Which of these do you actually bank versus sell? My instinct is to hoard everything from Aetherium up, plus Solmead, and sell the rest — but I'd like to hear from serious crafters what the real bottleneck materials are.
