I think it’s best to distinguish between the two different mochaAE products. There’s mocha AE CC (which ships with AE CC) and mocha AE V3.1 which requires an upgrade from mocha AE CC. More info here – https://www.imagineersystems.com/compare-products
Take note that mocha’s 3D Camera Solver is only available in the upgrades (as far as AE is concerned) to mochaAE V3.1 and mochaPro.
There are a few mocha 3D Camera Solves found in this search –

One of the results is this – https://vimeo.com/50599990 – which is a good example of 3D object tracking with mocha’s 3D Camera Solves.
What is important to note is that AE’s Camera Solves does not provide a viable solution for 3D Object Tracking, which is something the mocha does. Having said that, if an object moves rather slowly or subtle relatively to a camera move and its orientation then it is possible for AE to solve an object’s 3D-ness with respect to its position and orientation.
FWIW, AE’s 3D Camera Tracker is the go-to choice for 3D Camera Tracking as it does an extremely good job on most tracking tasks.
It’s really up to you to work on or practice with as types of footage as your time and interest can spare.
