For me, it's the Elixir Phosphor Bronze (not the standard Elixirs), particularly with that much mahogany.
All my string instruments have D'Addario stings. I have tried pretty much every string out there since I started playing guitar in 1964. IMHO they sound better and last longer than any of the others I've tried including Elixirs. I never use the strings that come on any guitar. Even a "new" guitar has old strings on it since it may have sat in a warehouse for a year before the store bought it, then it sat at the store for month before you bought it. Most guitars come strung with light gauge strings but I prefer medium gauge for thicker sound quality. My "go to" strings are the D'Addario J17 phosphorus bronze. I buy them by the box! Case in point - I just bought a new Taylor DDX. Of course it came strung with light gauge Elixirs. The first thing I did before even paying for it was to have the store re-string it with J17s, played it again and enjoyed the better sound. I can't put it down now.
I have stayed with them, and I actually really like them for recording...many do not and say you lose some brightness and punch due to the coating, but I find I get less "squeeks".
My 1996 Taylor 510 came with D'addario medium strings. played them for while then switched to Elixer Nano Mediums a few months later and have continued with them ever since.. just sound better to me... as a matter of interest my other guitars all have D'addario EXP17s. Have tried many many different strings over the years and always go back to D'addarios..except the Taylor..
