Need to be able to click on SharePoint list column to open form

Rick Brock You can use below JSON to open the default form on click of person name:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "button",
  "txtContent": "@currentField.title",
  "customRowAction": {
    "action": "defaultClick"
  },
  "style": {
	"border": "none",
	"background-color": "inherit"
  }
}

Reference: button elements 

Note: Using this JSON, you will loss the default hover action of person or group field (where you can see user details). Maybe adding some more JSON code you can achieve hover also. check above link for more information on column formatting.
