What you’re asking about is usually referred to as inlay on the forum, and there are lots of threads about that.
It’s hard to know what level of advice to give here, I’m not sure of your existing skill set. The bottom line is that this can be tricky to get right but it’s entirely doable.
Topics you’ll want to read about:
Inlay
Kerf adjustment
Path manipulation (aka node editing)
Flip-mating
Vector conversion of a raster image (if you’re starting with a raster)
If any of this is new to you I’d suggest searching the forum and seeing what it’s about. After that if you have direct questions I’m sure we’ll have direct answers.
One thing that is very useful is hard to search for, so I’ll drop it here.
And lastly as for padauk and wenge, they look outstanding together. Check out the “shockwave” design in this post:
