I don’t know if the OP is even looking at his/ her own thread but if I were to summarize and choose which Spanish of the three I would bend more towards 🇨🇺although just learning the language through studying and interaction with native speakers for practice is very helpful and enough. However, if one is in the Eastern part of the US Caribbean Spanish is what is common- news, sports, songs, NYC, NJ, Miami, Boston, that is the brand you are going to hear.
To the OP have fun learning Spanish. It is truly a beautiful language.
