it looks to me like any enterprise data tools support JDBC, so the Avatica JDBC driver should work?

I've spoken to a couple people who have got Metabase working to some extent although I don't know exactly how useful the integration is (I've also had this sort of working myself before)

which BI tools are most of interest?

there’s a plethora of different ways to move data into these data products, jdbc being just one… so weighing options
