Best phone all rounder I would is the galaxy s10 plus. It has sd card, headphone jack, charger in the box, free headphones in the box, mst, 4k screen, great camera and also its low price and also has charger in the box and has a glass body
Next I would say is any phone the galaxy s20 series or the galaxy note 20
They both have sd card slot, 4k screen, has headphones and a charger in the box, mst, glass body
The new s21 series have no sd card, no charger in the box, no headphones in the box, apart from the ultra, the other s21's all are stuck at 1080p screen, they all have a plastic body.
If you want the cheapest best deal, I would say get the s10 plus 512gb and then get a 1tb sd card. You will have plenty of space, more than the s21 series
