We've been having certificate/trust issues on DBeaver ever since switching from the MySQL 8 driver to CelerData's
starrocks-connector-j
driver. I see that the CelerData driver is not open source. Do any CelerData folks have advice on how to deal with these errors?

Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

you have an option to use either Starrocks driver or Arrow Driver, https://docs.starrocks.io/docs/unloading/arrow_flight/ both are open source.
