I'm not sure how this very long list of destinations fits with your use of the word "relaxation" unless you're able to devote several months to the trip. Be that as it may: you don't seem interested in visiting anywhere on the way to or from Asia and Australasia (in particular western US or Europe) so I can't see any good reason to consider a RTW.

... would be my preferred option. Book open jaws and/or make good use of stopover rules. Buy 'local' flights for cash or miles depending on what's a good deal, choosing the class of travel based on how long the segments are.
Your question and its responses will be moved soon, I hope, as this thread actually has a different purpose: a reference thread listing routes on which OW carriers operate F service.
