Default steps for optimizing storage from Apple
There are two types of messages that can be seen when Apple warns you about low disk space. It can be a popup message or a small reminder in the notifications center. They usually appear when the user has less than 10GB of free space available.
Once you click to save space by optimizing storage, your machine opens the Recommendations window and shows types of files that take up most of the space on your Mac. Also, the macOS system suggests you save space by using the following options:

Additional steps to recover more free space on Mac
1. Clean Downloads on Mac
Often Mac users don’t pay attention to the “Downloads” folder because they only use it to download apps and files from the web. In fact, this folder contains a lot of unneeded documents and files that occupy a chunk of disk memory.
Sort the files by size and see exactly how much space each file takes up. Then, remove unneeded files from the Downloads folder.
2. Remove unneeded localizations
Most programs contain multiple localization files, which take up your disk space. One file does not take up a lot of space, but all together can occupy a significant amount of your disk space. Again, they just clutter your files. Leave only those languages you need. If you do not speak Chinese, Indonesian, and Korean, they can be removed for most applications.
