kmonad VS hammerspoon

have you actually tried that? afaik they don't get you the perfect home row mods due to some limitations re. how they implement the tap vs hold logic

I use kmonad[1] to have QMK-like functionality on any keyboard.

You can create F13-F24 purely in software with key mapping tools. On Windows, one way is with the PowerToys Keyboard Manager: remap some unimportant keys to F13, F14, etc. Another way is with KMonad (cross platform), and define the keymap with KeyF13, KeyF14, etc.

There you have the software link : https://github.com/kmonad/kmonad

Other option I would suggest for any linux user with keyboards without QMK is to try KMonad https://github.com/kmonad/kmonad

Another option for hacking something like this together could be HammerSpoon. I’ve spent some time with it, but haven’t tried integrating with Apple Notes, I mostly did stuff at the file system level to keep it easy.

For basic window tiling, I stumbled across Hammerspoon and the MiroWindowsManager spoon.

I use hammerspoon a lot and it seemed like scheduling SelfControl could be done using it so I created Hammer Control. Check it out!

Hammerspoon - Price: Free Desktop automation tool for macOS that allows you to write Lua scripts to control your Mac.

Assuming no one has a cut-and-dried solution that just works, would something like this be possible with say, AppleScript or another scripting tool like Hammerspoon? I've not used either of these tools before, but would be open to seeking out a scripting solution on my own if it's viable. Or am I going to run into insurmountable security restrictions?

Spark (not the email app). There are others like Hotkey and Hammerspoon.

I have tried different tools for this including Rectangle, but I've finally settled with hammerspoon. It solves the problem of window-management but you can also use it to create custom keyboard shortcuts and much more.
