Derek,
Not totally sure what you’re asking for. Most inletting can be done with smaller straight chisels. If gouges are needed, it’s easier to go smaller than bigger. A #5, 5mm wide works good for the front of the lock plate.
For removing bulk from lock panels, side plates, inlays, I sometimes hog out material with a #11, 2mm, then remove the rest with a small flat chisel.
Other than that you will need to experiment to see what works for you.
As far as carving, if you stab in, you’ll meet dozens.
