Thank you for posting! I'm amazed at how helpful you guys are!
I'm not entirely sure there are EOL resistors. I don't see them at the panel and all of the sensors are recessed into door/window frames and glass break sensors. I will grab something to measure the resistance and see what I'll need to do in that regard.
I have 2 keypads that are separate runs. My concern is the data bus termination. On page 12 (and also page 6) of the installation manual,my setup will essentially be like the first diagram (without the expanders for now). I'm not sure how/where the terminating jumper should be installed (though it may be obvious once I receive the hardware). Is this something that is pretty easy to figure out?
My smoke detectors are not currently wired to the security panel, but I hope to do this in the future.
i do plan on getting zone expanders in the future (when I start to add automation). What is the issue with that?
The M1 data bus must have 2 terminators installed, one at each end of the data bus. The bus can be viewed as one long daisy chain, where a device or the M1 can be located at any position.
With 2 keypads, each wired as a home run, you end up with 2 branches of the bus (one for each keypad) and the M1 in the middle. In that case, you terminate each keypad.
T-- Keypad ------- M1 ------ Keypad --T
If you later add an expander, you could wire that between the M1 and one of the keypads. That's easy to do when the expander is located with the M1.
T-- Keypad ------- M1 ------ Expander ------ Keypad --T
That would require no change to the terminators. But if you wanted to locate the expander somewhere else, away from the M1, then it could get a bit more complicated. One way would be to daisy chain it off of one of the keypads and move the terminator to the expander (as in the diagram on page 12). Or you could use a M1DBHR. There are also other possibilities, such as running two cables (or a Catx cable) to the expander so make the data bus go out and back.
Elk has some helpful training videos on Youtube. It's worth taking several hours to view some of them, especially the basic training and RP2 videos.

(There are several version of the basic training video. All pretty much the same. Just recorded in different years).
There are many others beyond the basic training video.
