I am trying to set up my grid such that I can grid snap every 1/2 inch. No matter what I try, I can't get grid snap finer than 1 inch increments. Attached are screen shots from relevant Drawing Preferences tabs.

Hi,
Did you try below Unit settings "Imperial" instead of "Metric"?

Hi, and welcome to the QCAD forum.

I can't replicate your problem (3.32.4.0 Win7 32bit)
Your settings would set up a Grid with a minimal Grid size of 1/2 inch and a minimal Meta Grid of 12 inch.

Note that Grid settings other than auto are minimum values.
Zooming in, the Grid size won't drop below 1/2 inch.

Depending on an Application Preferences, the Grid/Meta Grid automatically adapts to the zoom state or are fixed.
When fixed it doesn't scale when zooming in/out, it is then always 1/2 and/or 12 inch apart.
If the minimal screen spacing is reached, it will be turned off to not clutter your entire screen.

Perhaps your current zoom state is much deeper than 1/2 inch screen-wide or much too wide for e.g. 10 pixels apart.

Did you try below Unit settings "Imperial" instead of "Metric"?

Is for Hatch and Linetype patterns and has no influence on the Grid/Meta Grid.
