I recently watched a video where the host mentioned that when using hand tools, you only need to flatten one face and square one edge of the wood. Is this true? If so, could someone explain what types of joinery this approach applies to and what doesn't?

Yep, you only need a reference face and edge for laying out your joinery. As long as the other sides are somewhat flat, perfection isn't necessary. This method was actually a common efficiency shortcut used by earlier woodworkers, so you're in good company!
It really depends on the project. For example, if you're making drawer boxes, all visible sides should be S4S since they'll be seen. But again, less visible areas can be a bit rougher. You want to aim for close accuracy without stressing over making everything perfectly smooth. Plus, there’s a lot of discussion about how modern woodworking standards have changed from traditional methods—check out some breakdowns by folks like Jennie Alexander for some eye-opening insights.
For glue-ups, you're right. You don't always need everything to be perfectly S4S. There's a lot of info online about how furniture parts that won’t be visible can be left a bit rough. Just focus on getting the joinery parts accurate; the less visible surfaces can be flattish and will save you a ton of time on planing large surfaces.
Thanks for the tips! It's good to know it's all about efficiency sometimes.
