Trying to be considerate, I tried to browse old posts on my usenet
server related to this topic, and I noticed that the product

Peltor H10A Professional Noise Canceling Earmuff

was used by some. It seems "healthy" to me not to have everything
completely muted, and being able to hear voices at normal voices
would be a plus (though I'm not sure how well this product would help
satisfy either of those goals).

Is the one above a "good, safe choice"? Any other models you might
recommend I consider? I suppose if I had a pair, I might start
wearing them when I mow the lawn, though that idea hadn't occurred to
me before.

They're just your basic earmuff. For the price, yeah, they're fine.
