Hi and welcome.
What sort of furniture?
I once made a larger cabinet out of marine ply, to house the innards of a record player.
The problem is the exposed laminations on any edges.
I solved that by using a coloured dye over some applied filler.
You can get faced plywood. But the problem is any cut with a jigsaw can disturb the laminations. Plywood is not like it used to be.
