Affinity Photo may be more powerful than you need, in which case try this bunch of Photos extensions. It includes fixes for distortion and chromatic aberration (for select lens makes and models, at least), white balance, noise reduction, Smart Lighting (which attempts to maximize dynamic range), and a haze reduction tool that makes local contrast adjustments. You don’t get much control, but if what you want are quick clean fixes, get this.
