After installing once, running ddev drupal install standard yields:
Drupal is already installed. If you want to reinstall, remove sites/default/files and sites/default/settings.php.
I'm able to delete these, but after running the command again, I get the same message and a .sqlite file appears in sites/default/files. It seems the only way to re-install drupal is to run ddev delete --omit-snapshot and then re-install in a fresh database.
