Sensor Provides rolling 90-day total - how to get daily values?

There isn’t anything native inside HA, you’ll have to use something external depending on what database you are using. If you’re on the native sqlite database there is an SQLiteWeb add-on, if you’re using mariaDB there is myPHPAdmin add-on. If you’re not running HAOS and can’t use add-ons, both those are available as docker containers also. There are other options out there as well.
