I moved at work from Ubuntu to Mac six months ago. I had AutoKey script for getting my most used password with keepassxc-cli and pasted it as text, which I had bound to Ctrl+F12. I tried to find an alternative to that on Mac and Hammerspoon was the most frequent search result. I couldn't find an easy enough example for me, though, so I went with Alfred + alfred-keepassxc workflow. It's completely different way to get passwords, how ever I prefer that now.

One funny thing while searching for information was that almost every Hammerspoon discussion had the mandatory "why not AppleScript?!" comment.
