One feature that I think could work will in Files: In MacOS when you select multiple files in Finder, you can right-click and choose "Rename" from the context menu. This opens up a dialog that gives you several options to rename the files, such as:
Replace Text: Find specific text in the filenames and replace it with something else.
Add Text: Append or prepend text to the filenames.
Format: Rename the files using a numbering sequence, a custom name, or with dates.
This feature is built into macOS and is quite powerful for managing files quickly
