Wrap single line text in the Title Column so that it breaks while maintaining hover/single click.

Hi CH4646 

You need to add:

  "customRowAction": {
    "action": "defaultClick"
  }

https://learn.microsoft.com/en-us/sharepoint/dev/declarative-customization/formatting-syntax-reference#customrowaction

If you like the JSON you currently have, it would become:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "style": {
    "box-sizing": "border-box",
    "padding": "0 2px",
    "overflow": "hidden",
    "text-overflow": "ellipsis"
  },
  "attributes": {
    "class": "sp-field-fontSizeMedium"
  },
  "txtContent": "[$Title]",
  "customRowAction": {
    "action": "defaultClick"
  }
}

If you want it to look just like standard SharePoint, then you would use:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "button",
  "style": {
    "box-sizing": "border-box",
    "padding": "0 2px",
    "overflow": "hidden",
    "text-overflow": "ellipsis"
  },
  "attributes": {
    "class": "ms-Link root_137a7565 nameField_c45bee6b clickable_c45bee6b  "
  },
  "txtContent": "[$Title]",
  "customRowAction": {
    "action": "defaultClick"
  }
}

That has all the same formatting in the "class"
