I generally recommend Lightroom as the first tier tool. It is capable of doing the most important post-processing tasks on RAW files as well as JPG and TIFF image files. It also has a powerful pass-through mechanism to work with image manipulation software such as Photoshop, Elements, Paintshop Pro, or The Gimp. The cool part is that all Lightroom processing is non-destructive and leaves the original source file unchanged* despite having the ability to work with many virtual copies and processing approaches.
While the processing strengths of Lightroom are usually highlighted, its cataloging and print facilities are very powerful and not quite as obvious. I prefer the non-subscription version and strongly suggest that even experienced users invest in the Martin Evening's excellent guide
LINK as a means to plumb Lightroom's full feature set.
There are also several open source tools with capabilities similar to Lightroom. Darktable is good for Linux and MacOS. RawTherapee is popular on Windows.

* The original source file is not overwritten unless the user specifically requests that processing information and metadata be inserted into the file EXIF section. This is technically a revision of the original file, but not required for routine processing.
