ACE has great stuff, their Panama is like F10 at this point, practically an IBL, so a lot of the wild traits have been bred out. Try their Honduras, it might be closer to what you're looking for, only an F2 from landrace. I haven't grown my pack yet, but I am crazy excited to. If you want reaaallll long flowering Central American genetics, @therealindican on IG has '72 Colombian IBL for dirt cheap. ACE Oldtimer Haze is also an old long-flowering Colombian.
@cabbagepaps on IG has "mordida" which is Bodhi's Acapulco Gold x Bodhi's Zipolite Oaxacan. He's a rad dude, maybe a mix of old Central American lines will set you right? Not a ton of real deal Panama Red around, except Coastal, but there's a lot of similar stuff available for reasonable prices.
