I’d also recommend laser cutting and I’d also recommend ply or MDF with your hardwood as a veneer. I have some previous experience cutting speaker grilles like this - not like your design but with an Art Nouveau cutout. It wouldn’t have held up with a sheet of hardwood with a grain.
I think with the black edges you’ll get with a laser cut, maybe rout the sides at 45° or 60° and then treat with a coat of satin Osmo oil, it’ll look quite stunning.
