I personally would not recommend the persephone for a first time wild betta keeper, and this is coming from someone who went and purchased fish from this complex as their first ever wilds. Even in the coccina complex they tend to be a bit more difficult to breed, and I know some hobbyists have different views, but IMO they need a very low hardness/pH to thrive.
Anything from the splendens complex seem to be very easy to keep and breed. I had a pair of Betta stiktos in a 20 litre tank and they spawned regularly without any real effort on my part. Being bubblenesters, this complex is one of the more aggressive ones. So be aware, some breeding pairs can live together full-time without issue, whereas, some may need to be kept separate unless being used for breeding. It all depends on the individual.
Otherwise, any of the mouthbrooding complexes are good, particularly the smaller mouthbrooding species. I always recommend the albimarginata complex because they breed like guppies, have endearing characters, and are not fussy about water conditions/tank set-up. However, if you have softer water and a larger tank, the foerschi complex contains some stunning species. The unimaculata complex is another good one if you want to work with large fish. I probably wouldn't recommend going out and purchasing a pair of Betta macrostoma right off the bat (expensive fish to lose), but the other species are very personable and generally easy breeders.
I personally prefer to work with wild-caught fish as my foundation breeding pair, as I have found the quality lacking in some species (particularly splendens complex where it seems like a lot of hybrids get passed around as pure). I will not sell a fish unless it is healthy and in top condition, but I have seen some wilds that looked pretty haggard getting passed around.
