Titebond is 'good stuff' and has a good reputation among wooden model builders. It is not always easy to find. A Google search on titebond glue will return links to a lot of vendors/sellers - both on-line and in-store sources.
Elmer's carpenter's wood glue (the yellow stuff) is also widely used and recognized as 'good stuff' for wooden model building purposes. It is more widely and readily available off the shelf from a broad range of stores - hardware, lumber, craft & hobby shops, even some grocery/household stores, etc.
My own experience with Elmer's is that it makes bonds between clean, bare pieces of wood that are stronger than the wood being bonded - any breaks that occur will happen near the glued joint, but not in the joint itself.
Titebond aside, 'white glue' often refers to glue intended for joining paper, as in school project types of applications. It can be used in model building, but generally is not a first choice for gluing wooden parts together.
A note of caution: Gorilla Glue is powerful glue, noted for its gap filling abilities. However, it is not well suited to model building because it uses a foaming formula to achieve its gap filling results. The foaming action can push the small parts used in model building apart, especially if not firmly clamped.
Epoxy glue can be used in places where very solid joints are needed - bulkheads glued to keel pieces, or parts that are expected to bear a lot of strain or vibration like motor mounts in R/C models, for example. Epoxied joints are not coming apart, so be sure you really want things permanently joined before applying epoxy glue!
Finally, read the label on the container and/or packaging for both intended applications and cautions/warnings about potential hazards - some glues are flammable, some release noxious fumes, some can burn skin, and so forth. Elmer's is pretty benign stuff, but don't eat it.
The ultimate information resource on glues and gluing things together is

which includes a very useful FAQ in addition to its 'single-shot' returns when
asked about gluing disparate substances together.
