Funny you should mention that... 7-zip is not available on macOS as a GUI (probably due to limitations on file managers maybe, since it can be used as one), and the command line never works for me with password protected archives. However, with Jd2 it works, as long as I supply the password before the archive downloads.

I do have an unpacker, but it doesn't work on everything (like password protected .7z files).

I could probably get a more robust file manager (something like Directory Opus for Windows, but I'm sure other options do exist on Macs) that has a built-in archiver that would do what Jd2 does, but for now Jd2 solves the minor issue.

Pretty sure you can disable archive extraction in settings if you don't want it to do that.
