At least some magnolia species also repel close neighbors.
Beech, F. grandifolia, may, but that may only be because of the
thick layer of dead leaves under them.

Not because of the leaves. It's the thick shade. Herbs that precede
beech leaves do well in spring in spite of the leaf layer on the ground.
After that, only yews can stand it.
