This is a 2007 XB12 S

I’ve never tried to post the link here but this is a video of what is going on.
Does anyone know of the resource that I could reference to be able to figure out if this is a pattern?

KEY ON....KILL SWITCH ON...TO PERFORM THE BELOW TEST.
NOTE: remove seat...remove both battery cables....thoroughly clean cable ends and batt terminals...then reattach. your current CEL often times caused by low voltage condition associated with loose/corroded/cracked cable ends/terminals.
your vid shows erratic idle speed and surging. typically a failing fuel pump.
do this:

First thing to do is locate your diagnostic test plug under the seat. It's an empty four pin connector. If you're looking at it with the pins facing you and the locking tab at the 12:00 position, the pins are numbered as follows:

Pin 1 -- upper right corner
Pin 2 -- lower right corner
Pin 3 -- lower left corner
Pin 4 -- upper left corner

With the ignition switch off, install a jumper wire across pins 1 and 2 in the diagnostic plug.

Turn the ignition switch to the ON position and wait approximately 8 seconds for the check engine light to start flashing.

All trouble codes are sent out as a series of flashes. To rettrieve the first digit of the code, simply observe the number of times the lamp flashes.

The transmission of a trouble code is always preceeded by six rapid flashes (about 3 per second). This transmission is followed by a 2 second pause in which the lamp is off. The lamp will then flash one or more times to indicate the first digit of the trouble code. The length of time that the lamp will be either on or off when indicating a trouble code is about 1 second in duration.

Following the transmission of the first digit in the trouble code, there will be another two second pause before the second digit is transmitted.

After the second digit is transmitted, there will be another 2 second pause. After the pause comes another intermission (six rapid flashes) after which the next stored code is transmitted in the same manner. Once all the trouble codes have been displayed, the sequence will repeat.

If all you observe is the rapid flashing, then no trouble codes have been stored.

When done, turn the ignition key off and remove the jumper wire.

There is no way to clear trouble codes using this method. The only way to clear codes without hooking the bike up to a computer is to take the bike through 50 start and run cycles (start engine, run for at least 30 seconds, shut it off).

The trouble codes are as follows:

11 Throttle position sensor
13 Oxygen sensor
14 Engine temperature sensor
15 Intake air temperature sensor
16 Battery voltage
21 Interactive muffler control (XB12 only)
23 Front fuell injector
24 Front ignition coil
25 Rear ignition coil
32 Rear fuell injector
33 Fuell pump
35 Tachometer
36 Cooling fan
44 Bank angle sensor
52, 53, 54, 55 ECM failure
56 Cam sync failure

Thank you so much for this info!

Just thinking ahead and preparing for the worst, how hard is it to remove and replace the fuel pump? Is it a pretty extensive repair?

Not too bad honestly. Get a factory manual. As far as Fuel Pumps...
