I see lots of free kitchen cabinets on Craigs list from people redoing a kitchen. Would this wood work good for a dob mount? I dont know a lot about wood, but most cabinets look like they are made of plywood.

For up to a 10 or 12 inch Dob, I don't think kitchen cabinet material would be a problem. For a large Dob with a big full-thickness mirror, you might want to consider structural plywood rather than furniture grade. Your mileage may vary.

Plywood is an expensive material to use for cabinets. Usually this is a wood chipboard and veneer on upper.

Most cabinets for kitchens and bathrooms if cheap are made of particle board and if higher grade are made of rather thin plywood. A sheet of 5'x5' 1/2 baltic birch will cost about $50 and is a much better choice of  material for a dob base. baltic birch has many more layers in its laminate structure and very few voids. A 1/2" sheet of baltic birch will have about 10 to 12 layers of veneer and a standard 1/2 ply with hardwood exterior will have about 5 to 7 layers with voids. Not saying not to use old cabinets as useful material but you may have some issues with structural integrity and stability. If you get lucky and find some cabinets made from 1/2 inch or better ply you could use it, or laminate some of the 1/4 to 3/8 inch stuff together.

Most cabinets are thin skins of plywood or particle board with real wood fronts where the doors and drawers are attached.

The exception would be high end stuff from very expensive homes or high quality commercial buildings and of course custom cabinets

One of my dobs is made from old pine cabinet doors and shelving. 1950s era stuff. Works fine. Most recent stuff will be particle board.

Just a side note, and a trivial thing, but all plywood has an odd number of veneer layers. It has something to so with grain orientations canceling out stresses to limit warping. Just tid bit from working as both a carpenter and at a plywood mill.
