Now, if I set the trackpad's Natural Scrolling to 1 or 0, it doesn't respect it. Unnatural scrolling regardless. If I set Natural scrolling to 1 for my mouse, it respects the setting, and reverses the scrolling each time I toggle 1 or 0.
I'd really like to find the simplest, most proper solution. Previously I was using xmodmap, but it only applies to some applications, so it was frustrating to sometimes be natural, sometimes reverse scrolling, depending on whether the app's GTK3/QT/GTK.
I'm a noob, so teaching me how to make the settings permanent or "sticky" after reboot would really help me, and every other noob with similar troubles.

It's probably this bug.
Here is more proper workaround than OP's, until the bug is fixed:
Find out your device's name by running
xinput
Create a file named
90-fix-for-LP1132063.conf
within/etc/X11/xorg.conf.d/
with this content (for enabling Natural Scrolling):I suggest setting this option, too:
It will enable simulating the left click via tapping the touchpad.
