For cropping audio files, QuickTime can do it. Look in its menus. Also transcoding video files (to what extent this might be “compression” depends on your use case). PDF page manipulation is the easiest thing on macOS, also quite robust usually. Just open the document in Preview and open the page sidebar. You can reorder or remove pages there; or drag and drop pages from other documents.
