What product would fit current-day NJPW the best?
I'm struggling to pick one and see so many different real world databases with a different one. However, I see most databases having "Wrestling As A Sport" as the core product, with either "Strong Puroresu" as the current or "Classic Mainstream Puroresu".
Here are the descriptions:
Classic Mainstream Puroresu
This is where a Japanese style has some western influence; match quality is crucial and wrestling is treated with respect, but there are flourishes of showmanship and larger than life characters can happily exist here.
Strong Puroresu
Heavily influenced by the martial arts and combat sports, this style revolves around realistic strikes and submissions - it's midway between Wrestling As A Sport and full-on Shoot Wrestling. Everything is treated very seriously.
Wrestling As A Sport
The stereotypical eastern style, this is where wrestling is treated as a legitimate sport. Fans want to see good quality matches with none of the hoopla that is associated with the western styles.
