So I'm thinking along a couple of lines he

1. Metal plate might not be a bad way to go. But instead of plopping the
plate over the hole, with brackets to hold it in place, I'm thinking of
a plate flush with the floor, built up to the height of the wood cover
(~1-1/2")) along the edge. I'm planning on getting a price on this
Monday. Once fabricated, I could just caulk the hell out of the ledge,
place the plate, then caulk the gap to seal it.

2. I'd like to get a couple bids from concrete contractors to fix the
hole. I'll both find out how they'd do it, and also get prices: it might
turn out to be cheaper overall to just have them do it, rather than do
it myself.

At this point, the only thing that gives me pause is the possibility of
weakening the existing slab by drilling into it for rebar dowels.
Everything else seems like overkill, and the people I've talked to
locally agree with me on that.
