Track Drone Footage & Export Camera to 3D Software 

Because she wants you to join the traning, fair enough isn't it? haha but i'm sure that you can figure it out with the info that is shown in this video..

I also use After Effects or Blender just for tracking

Here's no tracking software for only architectural visulization, it's just tracking software. 3DEqualizer is industry standart. SynthEyes also not bad. All depending on footage and task. Footage from this tutorial is simple and you can track it everywhere, even in davinci or after effects.

There is a resolve workflow

SynthEyes is another I use

If you are doing the modeling and the tracking then Blender does both. It is also free.

You're better off with the Mavic 3 Pro.

Probably your Z axis is wrong. You'll need to match with the refrence that you've created in PfTrackY

yes

You can but after effects it's not the ideal for that
