Not the OP nor knowledgeable in this area but I would suspect / hope postgres compatibility as a start. The last time I looked into whether I could use cockroachdb as a backend for my Airflow cluster, it wasn't possible due to compatibility issues.
You're actually 100% correct! CockroachDB is only 57.25% compatible with standard PostgreSQL (according to https://pgscorecard.com, which details the way it comes up with these numbers) whereas we are 100% compatible (and 100% open-source, whereas they are source-available).
