I agree that the heart beating emphasizes Godzilla will always be there as long as humanity continues their ways, but there doesn't seem to be any real indication that he's regenerating or if it will for certain be the same Godzilla--Especially from previously seen aspects in the movie I mentioned. (He didn't regenerate at all after King Ghidorah inflicted the wound on him.) Additionally, the spirits of Baragon, Mothra and King Ghidorah entered him and we don't know how that affected the heart. In the case of the Yamanto Beasts we see the spirits leave the creature they embody. We see no such thing when Godzilla is destroyed. Granted this could just be a case of something happening off screen, but there's just no emphasis to say one way or another.

Additionally, while no distinction is made between the two Godzillas in the GMK continuity, I don't think there's enough to suggest it's the same Godzilla either. As you mentioned, the mistake has been made in The Return of Godzilla as well and later contradicted.

As for Kiryu, I can actually see the armor adding close to 10 meters on the original Godzilla. The armor would have to (and do according to schematics) act as stilts to the skeleton. Additionally, the head crest would add a little faux height to the monster as well.
