Are these all the types of shifters?
Basically my question is, will 99%+ of bikes that people are riding fall into these 7 categories:
No Shifting (single speed)
Thumb (10-24 speed)
Grip Twist (5-24 speed)
Stem (5-12 speed)
Downtube (10-14 speed)
Integrated / Brifters (16-33 speed)
Bar-End (3-24 speed)
Other (3 speed)
Assuming thumb includes both thumb/index and just thumb

Downtube can be 10-30 speeds at least and maybe 33 if Shimano or Campy make 11-speed rear shifters in that format.
Barends are 3-30 at least as above.
A couple of less common types are Kelly Take-Offs (10-30 speeds) that mount downtube levers beside dropbar brake levers and Retroshifts (10-30) that mount downtube or barend levers directly on the shiftlever themselves.

you don't have to have a front derailleur to use more than 1 chainring,
its just more convenient..
and in addition to 'greasy finger shifting', with a chain tensioner /RD
and the 'quick beam' kit, flip flop hub with 1 or 2 cogs on each end,
and 2 chainrings,
Flip, taking off the wheel , & pull it back to tension the chain.
there is the front planetary internal gear system, 2 types,
button in the crank-arm center .. those shuttle thru the BB axle
(one side or the other, sticks up) , and handlebar cable shifted.
and the cable less kick back 2 speed..

A few points, firstly that there might have been 7-speed rear brifters made when they first started out, so it may be 14-33 speeds for those assuming you don't run a single chainring with them. I've also seen downtube shifters with no front derailleur, and you may even see the occasional 4-speed rear derailleur still on the road. Sturmey-Archer also make a downtube shifter for their 3-speed hubs.
There were also some front derailleurs shifted directly using a lever attached to the derailleur mechanism itself.
The car-style frame-mounted shift lever for the 3-speed hub on the Raleigh Chopper and the quadrant shifter that still turns up on very old 3-speeds around here also come to mind, although you may already have them covered under "other". The official designation for the standard shifter for the SA hub is a "shift trigger", by the way, if you do want to add that as its own category.

There are 7-speed brifters. I have one. You left out kick-back shifting with 2-speed rear hubs. Just pedal backwards to shift between high and low gear.

You could also be running a Campy 8spd system on a Shimano 7spd cassette or freewheel, since it's the same 5mm spacing. I had two such bikes.

Dave Moulton's blog has a great writeup.
The derailleur was operated by two levers on the right side of the bike’s rear seatstays, just below the rear brake. The top lever released the rear wheel, a lever below it operated a simple guide that moved the chain from one sprocket to the next.
Because this chain shifter was on the top portion of the chain, above the chainstay, it was necessary to back pedal to actually shift. The pull of the chain as it climbed over the teeth of the sprockets, moved the wheel forward. Once the shift was made, the rider’s weight automatically moved the wheel back and re-tensioned the chain.

A friend of mine has a Schwinn with a 4-speed automatic transmission that shifts based on pedal pressure.

The Cambio Corsa was a mind-bending bit of engineering IMO. Quite a leap just to come up with the idea.
I would love to come across an old machine so equipped...

I have 7-speed brifters. 1999 Shimano RSX.
Grip shifts have been on 3-speed bikes and went up to 27 speeds. You could probably make a 30-speed Gripshift bike by mixing groups but the Sram 10-speed group comes stock with a double up front.
Thumbshifters should be above-bar shifters only.
Trigger shifters would be the thumb + index finger.
Rapid fire (without the +) used to be called below-bar thumbshifters or push button thumbshifters back in the day.
Add Wishbone shifters:

Add Rocker shifters (that's what I call 'em, anyways.)

Also top tube shifters, as the Sturmey Archer quadrant and some old French bikes:

I reckon electronic shifting needs to be added as well.
Old School Mavic stuff, as well as the new stuff from Shimano and Campagnolo.

The Schwinn enthusiasts would want to include the top-tube mounted "Stik-Shift", available in 3- and 5-speed versions:
