"source-available" usually means you don't want contributions and forks, is that the case?

Are you getting anything by making the source available? Maybe you should make it proprietary.

There are some licenses like the LGPL which will forbid some companies to bundling your software in some ways. This license is forbidden at Google, as an example.

Which brings me to the topic of open source licenses and corporations. If you're hoping some big company will use and sponsor your project, they usually have strict license requirements (anything "custom" or outside the OSI-approved list will need extra approvals internally).
