I found and interesting article on this topic from Samford University (April 2022). This person was a Senior Marketing and Finance student with concentrations in Data Analytics and Sports Marketing. He wanted to understand the correlation between MLB winning % and the game's stats.
Key Points:
> Run Differential is the most correlated stat for winning % in MLB. No shocker here. You score more than you allow --> You win more.
> Various pitching stats (ERA, WHIP, FIP, etc...) are more leveraging than offensive stats for a team to be a winner. The "so what" of this point is that, stopping runs is more indicative of a winning team than scoring runs.

So, long-term, as a general rule to consider....
If you are picking a team to win, they should have a higher run differential than their opponent. If the run differential is close between them, then see which team allows the fewest runs.
Obviously, this is just a general rule of thumb but it may help your selection process.
