comment How do electricians quickly choose electrical box sizes?
@DMoore What I am trying to say is most applications are pretty obvious, especially if you are not working with a very crammed box or a shallow box. I think through how many cables are coming into a box before I choose the size, and I try to use deep boxes to avoid having to worry. No, it is not fast or automatic when you get beyond simple configurations.

@OrganicLawnDIY I wholly agree with the fastening on the bottom when using a french cleat. The nature of the art work seemed to preclude that. Your side braces help.

@HenryJackson Of course they should be! Thanks, I'll clarify. And you are welcome to edit directly anytime.

comment Two Three Way Switches w 14/2
I tried to explain more thoroughly. But the question is not about three switches (which do require a 4-way switch). And the same number of cables is needed in a three switch configuration; the 4-way just sits between the travelers.

@Mazura And then you pull out the charts (and your hair).

comment Two Three Way Switches w 14/2
@Scivitri In some (odd) configurations, 14/2 between the switches could work if the load was beyond the second switch on the circuit and already had a neutral.

comment Two Three Way Switches w 14/2
A bit of clarification needed. Do you already have two switches controlling the device or only one? Are you trying to add a second switch or a third? (Same question, just 2 ways of saying it.)

comment Help with electrical plan. What's right, wrong, suggestions?
Switches that control lights form two locations are called 3-way (it has 3 terminals) and diagrammed S3. The middle switch in a three switch configuration is called a 4-way (4 terminals), and is diagrammed S4. Also, there needs to be traveler wires running between each 3-way and 4-way switch. Your upper right circuit lacks that connection.

How thick is the insulation, and how much do you need to remove?

Not a bad point, but I still don't like that tension force in drywall.

comment Dry wall, mounting 13KG whiteboard
Actually, toggle bolts (especially the newer strap types) spread the load over the surface area of the toggle, about 1/2 x 2, about 1 square inch. Screw in anchors (better than the tubular ones) rely on the crumbling strength of a very small surface area along the length of the hole in which they sit. I haven't seen test data on pullout forces, but I think the new toggles would win. +1 for pushing for a stud finder and stud mounting.
