Are there any standard source-available licenses?

For open source software, I can easily use a widely-used open source license (e.g. MIT, Apache, GPLv3, MPLv2, etc.). However, source-available licenses are less easy to find.

Are there any source-available licenses that I can readily copy to apply to my software? I am hesitant to copy the source-available licenses listed on Wikipedia because license texts are copyrighted by default and should not be copied without permission from the author of the license text.

Specifically, I am looking for a source-available license that has conditions similar to the GitLab Enterprise Edition (EE) license that I can use for my software.
