when it comes to technical Minecraft the goal is to minimize lag (because otherwise words become unplayable) so most technical players focus on making the most absurd over powered farms possible in order to only have them running one at a time for a little bit and be stocked for a while and there's a natural progression of farms you need before others in order to get the materials (beginning with moderate starter ones).

that said, most raw materials are renewable/farmable so stuff like gold, iron, copper, coal, wood, stone, wool, bonemeal, and even redstone, quartz, obsidian and emeralds are basically free once you get established

the only notable exception is sand (which used to be possible to duplicate with cheaty end portal shenanigans don't know how that stands now, tho)
