I seem to have found the solution. First I need to snap vertices together by distance. In my case it took a choice of 0.04 as "tolerance" to get most overlapping vertices in the exact same position. The thing to check before I proceed is whether any surfaces have been lost in the process. If it still looks OK I proceed to "optimize vertices" and then to "optimize surfaces". I got rid of more than 70 redundant vertices.

In retrospect, I should have cleaned up the model before I started working on it. It was an X-Plane model that I imported to add more detail. It looked basic but fine and I didn't notice all the overlapping surfaces / stacked vertices until I had reworked it extensively. Now, I do understand that most sims like triangulated models (even though I don't know why) but I fail to see why overlapping surfaces / redundant vertices in (next to) the same position help in any way.

In any event, "snap vertices together" at 0.04 before any optimizing did the trick.
