Avoid/Minimize Sprites extrapolation in 2D while camera changes size

Its a common complaint that unity's 2D cameras arent the best as when moving sometimes the sprites can flicker, especially when the camera is changing sizes. Now i know there is a fix to this by having the camera orthographic size changing to match the pixels per units of the sprites, theres an equasion involved which i cant quite remember but the gist is it forces your camera to a certain size depending on the screen resolution. I want to have the ability to zoom out in my game so this would obviously not work and im looking for ways to minimize or fix this issue.

Anyways i havnt decided on a sprite size yet but i was wondering if there were any methods of minimizing this, perhaps making the sprites larger so the effect isn't as noticeable.

Are there any other methods available when making my sprites to minimize or prevent this effect? any advice would be much appreciated.
