The spindle override feature implementation in GRBL is unintuitive and I was actually considering to remove it from the overrides panel.
From the GRBL protocol specification you can read the following:
0x9E : Toggle Spindle Stop
Toggles spindle enable or disable state immediately, but only while in the HOLD state.
The command is otherwise ignored, especially while in motion. This prevents accidental disabling during a job that can either destroy the part/machine or cause personal injury. Industrial machines handle the spindle stop override similarly.
When motion restarts via cycle start, the last spindle state will be restored and wait 4.0 seconds (configurable) before resuming the tool path. This ensures the user doesn't forget to turn it back on.
While disabled, spindle speed override values may still be altered and will be in effect once the spindle is re-enabled.
If a safety door is opened, the DOOR state will supersede the spindle stop override, where it will manage the spindle re-energizing itself upon closing the door and resuming. The prior spindle stop override state is cleared and reset.

This worked just fine for me, recheck your settings

Spindle control works, however the M5 command for stopping the spindle will still make the status report a spindle speed. I will post a bug report to the FluidNC team.

Maybe my SpeedMap is too long. After I changed the SpeedMap to be the same as yours (10V as your PWM) , M3 and M5 can control the spindle normally.
However, the Spindle toggle button in the overrides panel is still unresponsive (no command is sent in the Console after clicking).
The sliding bar can control the spindle speed
