Is there an equivalent of YC's SAFE doc for royalties, musicians and creators?

I am looking for a standard, relatively fair document that is easy to understand that can help musicians and creators manage royalties, endorsements, promotions etc. The SAFE from YC kind of does this for funding rounds for entrepreneurs. Some cases that I am looking at use cases for these docs would be: 1) A musician/creator having their work used in films, commercials etc 2) A creator endorsing, promoting or advertising a brand 3) A creator using a bigger channel to push their content, i.e. creator gives their work to a larger channel with distribution 4) An artist signing with a label 5) An artist performing at an event 6) An artist becoming a brand ambassador 7) A creator's residuals I wouldn't expect all these to have one universal doc. I actually think they would be individual docs. I think what I am looking for is a doc that highlights in simple terms all the important stuff when signing such contracts in somewhat easy to understand language. Terms would obviously be flexible and determined between parties but the doc should have all the terms that need to be addressed at the very least and have them clearly explained. Any assistance with this would be greatly appreciated
