You've already found your answer, there is no one "best" kind of glue. Each of the adhesives you've mentioned has its advantages and disadvantages. Each is best suited for a particular task. Which adhesives you choose to use and how you apply them is part of the "art" to building your kit.

A quality carpenter's glue or wood glue (Tite Bond, etc.) is non-toxic and will provide strong, lightweight joints. Epoxy is heavy, but will provide very strong joints in critical areas like when attaching firewalls or joining wing-halves. Epoxy can also be thinned with denatured alcohol and used to fuel-proof area of the plane. CA glue is lightweight and very strong, but its toxicity makes it hazardous to work with unless particular attention is paid to ventilation. CA will be valuable in areas where instant setting is helpful (thin CA) or where a less-than-perfect fit prevents wood glue from creating a strong, reliable joint (thick CA).

If you want your kit to come out light and strong and durable, you will need to buy more than one bottle of glue.

Good luck and good shopping!
