Hi @jerrac and welcome to the InfluxDB forum.
Yes, your plan to use InfluxQL with InfluxDB2 is fine (I prefer Flux, but hey ho). To really be ready for the future, you can use SQL with InfluxDB Cloud v3 (and then if / when an on-prem version is released, you can install and transition to that).
For Grafana, check out the end of this thread.
AFAIK, InfluxDB2’s UI does not support InfluxQL (only Flux), but I might be wrong.
