I was in a similar situation in 2021, and my requirements were small size, no notch and headphone jack. I didn't like Samsung (the android from Samsung is fundamentally different from the other androids) and wanted to avoid xiaomi and other similar brands due to the ads bloatware.

The size requirement was basically impossible, but I switched it to a width requirement instead, and I found the Sony Xperia 10 III.

Pros: One of the smallest widths, no notch, jack, and a minor modified android (no stock, but pretty close).

Cons: too tall (but at least the small width makes it a easier to use with one hand), medium-bad camera (for some reason, although I don't care) and some preinstalled apps (like Facebook, but you can remove/disable them with adb).

Overall I'm pretty happy with it, and I'm considering another Xperia as a replacement if this one starts to fail (more than 4 years now, but still fine)
