S&g is a faster construction but both take the same time to finish and outfit.
Theoretically strip will provide a better shape, leaving aside what defines better, but for practical use an eight panel hull is getting pretty close to strip.
Four panel hulls are conceptually neat and build up faster than eight panels just as eight panel build up faster than strip. Four panel hulls can be designed well but some seem to have handling characteristics that are a consequence of construction technique and not design intention.. You could call a strip boat an N-panel hull.
4mm okoume ply is very good stuff but like strip the weight and type of glass you put on the wood is a major factor in strength/durability.
While epoxy/wood kayak builders talk about the light weight of their constructions, and sellers of kits talk about the light weight compared to commercial fiberglass composite kayaks they really aren't that far apart in weight once you build to similar levels of cosmetic and structural durability. From a cost standpoint a plastic kayak will be cheaper.
Keep gathering information. Your shop space should ideally be a constant temp above 65 degrees, 60 is doable below that and epoxy cure rates slow down requiring faster and thinner epoxies and more skill. Above 75 degrees cure rate is brisk and batches should be smaller. Above 85 find slow epoxies and work neat and quickly.
Get lots of gloves, keep vinegar and alcohol nearby for cleaning skin and tools. Once sensitized to epoxy always sensitized.
you might consider making a smaller epoxy/wood double and a skin on frame single instead of one big ship. Or two S&G. Skin on frame can make a very light kayak and a smaller double will make for easier transport. Also from a kid perspective it'll be a lot more fun piloting your own craft than being in another grown up vehicle. From skills development the'll learn paddling , rolling and rescues faster
