I have to laminate a piece of 1/8 plywood to a section of 3/4 plywood as a repair. What adhesive would be best, wood glue, or contact cement. If wood glue which?

My first choice is wood glue. And any brand should do fine, including TiteBond (I, II, or III) and Elmers, which are probably the most common.
Contact cement is not something I would consider in woodworking. However, I just found this interesting quote from an old article on our site that makes me think it could have some useful applications:
Contact cements are thermoplastics applied by double spreading and allowed to dry until no longer tacky. When the adhesive layers aretouched together, cohesive bonding forms up to two-thirds of the ultimate strength immediately, hence the term contact cement.
They will bond to many materials in addition to wood. Although contact cements have lower strength than conventional adhesives they are suited to many applications where clamping pressure would be difficult to apply and sustain and where high strength is not a requirement.
Contact cements are perhaps best known for applying plastic laminates to counter tops. They are liable to fail about 120° F. Water-soluble formulations are available but have relatively low moisture resistance. A major disadvantage is the zero closed assembly time: surfaces bond immediately and cannotbe repositioned once contact is made.
