Quick Answer

Your first redstone farm should solve resource pressure, not show off complexity. Early and midgame worlds should prioritize low-cost, frequently used, easy-to-repair farms such as sugar cane, bamboo, crops, XP, and basic mob drops.

Before Building

Ask four questions before every farm: do you have the materials, do you urgently need the output, will it create lag, and can you repair it quickly? If two answers are uncertain, build a simpler version first.
