@evanmcd The error Unknown config name ... comes from using sfdx force:config:set. You can not use sfdcLoginUrl as a config variable. Instead, that needs to go in your sfdx-project.json file. If you want to set a config var, you can try sfdx force:config:set instanceUrl=https://test.salesforce.com. I think the auth commands will use the following order:

1. --instanceurl flag on the commands
2. sfdcLoginUrl in the sfdx-project.json file
3. instanceUrl in force:config:set
4. SFDX_INSTANCE_URL envvar

@evanmcd - Is the sfdcLoginUrl property at the top level of your sfdx-project.json file? For example:

{
  "packageDirectories": [
    {
      "path": "force-app",
      "default": true
    },
    {
      "path": "unpackaged"
    },
    {
      "path": "utils"
    }
  ],
  "namespace": "",
  "sfdcLoginUrl": "https://test.salesforce.com",
  "sourceApiVersion": "44.0"
}
