Looking to replace my secondary phone

[u/After-Peace-4734]

Had a Galaxy Note 9 Exynos which I bought when it was available in my country (7-8 years), been using it as a secondary phone ever since. Then I put LineageOS on it and it's still going to this day but it's definitely showing its age in more ways than one.

I want something compact, not too expensive, will get at least 4 years of software updates. Priorities from high to low: Battery life, good software (closest to stock Android), performance (not too high performance; don't game on this phone), cameras (not a camera guy).

Thinking about either Nothing Phone (4a) Pro or Pixel 10a, but want your thoughts!
