Luckily we do not have to rely on opinion. Take this 1204x800 real-world photo which is less than 80KB: https://raw.githubusercontent.com/link-u/avif-sample-images/master/fox.profile0.8bpc.yuv420.avif https://raw.githubusercontent.com/link-u/avif-sample-images/... That's slightly less than half the height and width of your phone's screen respectively, so a decent representative of a model photo dimensions (which are usually widgets smaller than the screen). Model images would compress much better as they are edited to be much cleaner with smoothed solid colors and either solid or transparent backgrounds, and for something like a toothbrush you'd have an incredibly narrow image geometry making the final image likely much smaller. Even if you'd consider this image too small or too low resolution, bumping those would not push us past 150 or maybe maximum 200KB. (That repo has plenty of examples of other configuration examples if one is curious.)
