I've not seen Adobe Dimension as a commonly used program for creating 3D printable miniatures. In the web site, it's described as a 2D and 3D scene creator. You'd want a program known for creating models for 3D printing.

Fusion 360 is a good engineering type program, usually used for highly technical creations, but it does have a sculpting feature. Zbrush is very organic, Sculptris from the same company also organic, as is Meshmixer. Rhino3D can be used for such creations. There are likely many more better suited. Blender is another, but can create models that will not print on a 3D printer, unless special care is exercised.

I've not seen anyone use denatured alcohol, possibly for lack of efficacy. Isopropyl alcohol has to be in high concentration, upwards of 90 percent, while some YouTubers use green cleaners with equal success.

You must have missed those two chapters in your homework assignment.

The rest of your list is pretty well thought out.
