I ended up using Shortcuts to publish a set of screenshots from an always-on Mac every 10 minutes or so for a set of shared, family AirTags: http://vitor.io/android-airtags
I couldn't reliably get iOS to do the same, and my tests of an Android-compatible tag found it was detected much less often than an AirTag riding along with it.
