I use sectioning in CAD extensively. Sometimes its the only way to properly see things, especially with more complex assemblies. Other times you need to define a plane at some specific orientation different than the 3 primary planes and (assuming F360 works the same) any plane can be sectioned. Or a section can be offset from a plane by X amount. Or you can hide certain components but not others & section through that. Or you can save that 'view' for later reference. The possibilities are nearly endless. I use to do a lot of manual drafting so I know how much work goes into drawing things that a computer can bang out in a couple mouse clicks. But they still can't quite do that classic ink & airbrush like you use to see back in the day. That took an artist eye.
