Migration Assistant does this quite well. This is the built-in first-run cloning tool when you start a new Mac. I'm on maybe the fifth or sixth generation of cloned user environment in however many years. Apps, preferences, data, all copied from older machines to newer ones. I recently ran into a scenario where that didn't work (on an iPhone) when a device is managed by MDM. This is the first time I've seen it fail other than 15 years ago on an edge case. For a Mac, Homebrew has an option (or maybe another tool leverages it) to create a manifest of sorts to reinstall all the right tools. That's a bit different. I know that Casey Liss, of the Accidental Tech Podcast (https://www.caseyliss.com https://www.caseyliss.com, https://atp.fm https://atp.fm) has talked about it on his blog. I just woke up, so apologies for not finding it for you.
