Welcome to the ED forums!
Some switches cannot be mapped to keyboard/joystick yet, because input commands are missing (e.g. complete left panel). This is of course known (e.g. ticket #28106) and being worked on. Remember the F-86F is still in beta.
You are also correct about the inconsistencies. The scheme of command mapping should not only be consistent across the different forms of cockpit controls, but consistent across all modules.
It is known that several users and especially cockpit builders want all individual switch positions mappable by default. I think this will be done in the future, even if this will produce an enormous amount of input commands (see for example the 9 commands for the 7-position Drop Tank Selector Switch in the attachment).
In the meantime you can take a look at Madcat's thread with lua edits:
