@nclsndr I suspect that those settings control something else? I say that because my com.apple.Accessibility.KeyRepeatEnabled is 0 but of course hold-to-repeat actually works. My guess is that this "KeyRepeat" only refers to some accessibility feature that might have key repeat.

Also I noticed that on my Mojave machine those keys don't exist at all, but they do on Catalina. Catalina introduced a bunch of new accessibility features so my guess is it's related to one of those. I'd be curious to hear if you figure this out!

$ defaults read com.apple.Accessibility.KeyRepeatEnabled
{
    AXSClassicInvertColorsPreference = 0;
    AccessibilityEnabled = 1;
    ApplicationAccessibilityEnabled = 1;
    AssistiveTouchScannerEnabled = 0;
    CommandAndControlEnabled = 0;
    DarkenSystemColors = 0;
    DifferentiateWithoutColor = 0;
    EnhancedBackgroundContrastEnabled = 0;
    FullKeyboardAccessEnabled = 0;
    FullKeyboardAccessFocusRingEnabled = 1;
    GrayscaleDisplay = 0;
    InvertColorsEnabled = 0;
    KeyRepeatEnabled = 0;
    ReduceMotionEnabled = 0;
    VoiceOverTouchEnabled = 0;
    ZoomTouchEnabled = 0;
}

The issue I have with KeyRepeat is that you can't have it faster than 1. Doesn't accept floating-point values from what I saw.
Used to work around this using Karabiner (actually not Karabiner but the app that it replaced) but that was apparently not possible anymore since some MacOS version.

I imagine the com.apple.Accessibility. KeyRepeatInterval relates to key repeat speed on virtual accessibility keyboard
If anyone figures out how to increase key repeat interval beyond 1 please do reach out 🙏🏻
