I've looked online, but haven't found one. Is there any sort of "matrix" available that puts shift lever boss type on one axis and shift lever on the other, and remarks on each pair's compatibility?

Ideally, this would include bosses that include the following (and any others that might be useful): downtube braze on, downtube clamped on, barend "pods", "thumbie pods", stem-mounted.

Each type on each axis would be collapsed based on same-shape/same-size with some notes on which specific items fall into each type category. So, something like this:

      Bosses:
             Shimano d/t "A"    Campagnolo d/t "A"    Paul Thumbies    ....
Levers:    ======================================================================
Shimano   |                   |                     |               |
  333     |                   |                     |               |
          |----------------------------------------------------------------------
Campagnolo|                   |                     |               |
SR "A"    |                   |                     |               |
          |----------------------------------------------------------------------
Simplex   |                   |                     |               |
   "A"    |                   |                     |               |
          |----------------------------------------------------------------------
   ...    | ...

Bosses:
Shimano d/t "A": PICTURE.  DESCRIPTION.   DIMENSIONS.  IDENTIFYING CHARACTERISTICS. ETC.
Campagnolo d/t "A": PICTURE.  DESCRIPTION.   DIMENSIONS.  IDENTIFYING CHARACTERISTICS. ETC.
...
Levers:
Simplex "A": etc. etc.

As far as I know shift lever bosses are one of the few things that are actually fairly standard across all manufacturers. –  Fred the Magic Wonder Dog Jun 3 at 0:38
    
@FredtheMagicWonderDog, That's a help, for sure. Do you happen to know about between manufacturer compatibility? That would be alright if all types in the requested matrix are simply categorized by manufacturer. –  PositiveK Jun 3 at 15:24
    
I have always been able to use anything on anything, but I haven't used everything. Campy shift levers from the mid 60's fit on modern downtube bosses and vice versa. I'm sure there is a counter example somewhere, but I've never run into it. –  Fred the Magic Wonder Dog Jun 3 at 16:32
