If you still have this issue, you could try the stroke to path method :
duplicate the path you want to offset, give this duplicate a stroke width equal to twice the offset you want.
do path > stroke to path (Ctrl + Alt + C) then path > break apart (Ctrl + Shift + K) : assuming your path is closed*, this should lead to two paths : remove the one corresponding to the outset and keep the one corresponding to the inset.
* with an open path, you have, before breaking apart, you have to select the nodes of the extremities and remove the segments between (Ctrl + Alt + BackSpace)
BTW : for a CNC use, remember to flatten LPE (they won't be dealt by any other software, AFAIK)
Yes, I have tried the other types and the results are not what we need. This affect only occurs when we reduce the offset (using a negative offset). Positive offsets are fine. Instead of Miter, I used the first Extrapolated option and have less hook now, but still not good enough.

HELP!!!
Hi, just found the Path Effects -> Offset in trying to figure out designs for inlays. Kerf!!! Little booger!
Okay, the red outline is the original image. The blue is the negative offset. Image 2 is the settings used.
Notice that two nodes have a weird hook. I do not know how this happens and cannot resolve it.
Have you already tried another „Join:“ type than „Miter“?

Also, with this investigation to determine why this is happening, I turned on the "handles" of each path: original and then negative offset.
Very interesting, but still do not know why this is happening:
Original Line handles
Negative offset line handles
Can we have this portion at least as Inkscape SVG please?
Here you go
Please change these 2 nodes to "smooth nodes" or delete them at all as they are not necessary for the curvature:
Wow! I very much appreciate you checking out that drawing. Removing those two nodes changed everything.
Okay, I have learned through this process how to cut out jigs (or inlay hosts) and the inlay objects that are very tight.
Salute to all of you!!!!!
