For your use case, I would say 8gb of RAM is good enough for media consumption. The screen size on your S10+ is close to the S23+ so if you’re comfortable with the S10+ screen size it’s just a tiny bit bigger on the S23+. The S23 Ultra is quite big and boxy but if you use your phone to watch videos a lot you might like its big size.
The price difference between all the S23 models comes down to how much you value their size and maybe battery too. Bigger models have bigger batteries but also bigger displays. The Snapdragon 8 Gen 2 chip is great at performance and battery but if you charge your phone through the night when you sleep, the battery shouldn’t be a problem to last you the whole day.
