I'm afraid I'm unqualified to answer this question, but I'd use what I'm using now.

Diafine as my developer, Macophot UP100 as my film, 6x6 the format. 9 by 9 inch enlargements look very good, tonality is great even on underexposed negs (selenium intensification helps, though). Time and temperature are not factors, so if the climate changes on the island, my negs wouldn't. Also, the inablitiy to do N+ and N- developing doesn't bother me, as I never do those anyway, and VC paper gives me plenty of lee-way on contrast.

Fixer would be TF-4, because of the shorter washing time, and independence from hypo-clear.

Still working on the paper/developer thing, though.
