I would contend that furniture and cabinet making goes much easier with precise cuts and Square cuts. Much like building the foundation to a building...if it’s right the rest goes easier.
When I need square cuts on my parts, especially sheet goods I go to my track saw and rails with a CNC or accurate pattern of holes. This can provide high accuracy that takes expensive machinery to duplicate in my opinion. Another option is to cut and then take to a precise shooting board and plane.

Most of my woodworking doesn't have to be precise down to a degree, but sometimes it does. One guy on YouTube recommended an "engineer's square," rather than the kind used by contractors because they are more accurate. As I said, absolute precision usually isn't usually a requirement for me, but I'm trying to decide which one of those magnetic cubes I should get. I'll have to do the double line test with all my squares to see how accurate they are.
