I’ve read through a few QAs regarding PVs/PVCs and understand ReadWriteOnce is supported, creates a DO Storage Block and shares with a Node.
When 3 nodes for HA are deployed, what happens? – do 3 storage blocks get created. Would my config have to be adjusted to consider 3 PVCs?
My use case would be fine with 3 separate storage blocks - nginx caching - but ReadWriteMany would be better.

As of the time being, one DigitalOcean Block storage can only be mounted to a single node.
Indeed, what you’ve mentioned of using 3 different block storages would be the way to go.
Alternatively, depending on your usecase, for storing static files, I could suggest considering an S3 storage like the DigitalOcean spaces. That way each of your services would be able to write to the S3 storage independently, and the above limitations would not apply.
