Datalogging on Arduino (and compatibles): A comprehensive guide

I’ve used a lot of different configurations of Arduino-related gear as datalogging utilities. So here’s a comprehensive guide on what’s possible, how to set up stuff and on what you can expect regarding accuracy, battery life and logging speed.
