IANAL, but the Polyform Project (https://polyformproject.org/) apparently are, and they drafted a suite of licenses for these purposes.

Also, I'm not sure how anathema AGPL is. It's true I rarely see AGPL projects being hosted by big clouds, but AGPL is also just less popular as a license. I know AWS hosts AGPL Grafana, but iirc, they had to work out some deal with upstream.
