My Choice
I would choose the OnePlus 9.
While the Samsung Galaxy A12 has the edge in battery size and an extra lens for some photographic scenarios, the OnePlus 9 wins in almost every other area that is important to me. The performance difference is massive, ensuring the phone would feel snappy and responsive for years. The display is significantly better, which would improve my enjoyment every time I look at the phone, especially while watching videos and playing games. The faster charging, more advanced camera, stereo speakers, and modern connectivity all contribute to a more premium user experience. While I do appreciate having a telephoto and depth lens for some shots, the vastly better main and ultrawide cameras on the OnePlus 9 make the trade off more than worthwhile.
Though the price is higher, for the increased enjoyment and performance, the OnePlus 9 is a much better investment for my needs.
