I realize the ordinances use the word “noxious”, but the word means
harmful. Harmful to what?

The 'natural' environment? [which, IMO includes mowed lawns]

And which plants are the ordinances
referring to? Actually, there is no list of noxious plants,

Sure there are--

Both federal and state lists. And I'll bet some counties have lists.

Birds would be better served if we didn't mow. In unmowed forest
preserves birds thrive. In any case, cutting grass is unnatural.

I'm with you on the anti-mowing crusade-- I've never understood
anyone's fascination with 'well manicured' grass. But some birds
[bluebirds, robins, doves . . . probably others] prefer short grass.
