One thing I’ve learned over decades of home/DIY projects is it’s usually better to intentionally target a small overlap/reveal rather than trying to have two materials match perfectly.
If you have a piece of door trim that exactly matches the piece behind, any imperfections or subsequent wood movement will be unsightly. If you instead target a 1/4” reveal, imperfections and slight wood movement are wildly less noticeable.
This is “build so the 1/32” imperfection/movement doesn’t matter at all” rather than trying to halve or quarter it. (If you can make something monolithic after attaching, such as a plaster wall, you don't have to do this, but wood furniture and trim often has these intentional offsets.)
One thing I learned from theater set construction is that you can slap some gaffer's tape and paint over any flaws, and the audience will never notice.
The audience is like 25+ feet away to be fair. A little different in your kitchen.
Technical aspects to the trade are a different issue, I feel. "Wood moves, design for it" is a technical aspect of woodworking which comes up frequently. You learn about the medium (same for 3D printing, welding, electronics), and make use of that knowledge. The medium is far from the ideal stuff you might have thought - the more knowledgeable worker makes use of that awareness. It's not a question of guiding your effort through chaos but understanding that physics is NOT all chaos. "Wood moves" is not this big mystery - it's just the reality of the medium.
This comes up a lot in investing and economics also. The difference between the naive view and a bit more awareness of how the world works is not some kind of deep conspiracy and "magic recipe" to be discovered. It's just how the world is.
