Afraid of paying a monthly subscription fee for commercial software products when you might only need just a good raw editor? Take a look at the free open source software called darktable! Originally only available for Linux, you can now install it on Windows as well: https://www.darktable.org/
What I really like about darktable is the very easy user interface without layers, and the features to remove chromatic aberrations. There are even some open source lens profiles available for vintage lenses to correct vignetting and distortions. Check this good darktable tutorial here:
