Template selection

Would like a template selection with just Content selection other than Blank, Title, Title and Content so I can add text content without a title

I assume this is a slide template that you are talking about. You can create your own with as much or as little content as you choose.
In the slide menu, start a new slide. Create information - images text etc. as you want. It is also a good idea to create an area for free text, with the desired font size and other settings so you don't have to do it from scratch each time.
Then, when you are happy, you can save it as a template, giving it a suitable name. that template is then available for you and everyone else in your account to use.
It is possible to edit the template, but the usability is very poor. Start a new slide, using the template. Make the required changes to the template and then save it as a template again. However, you will have to remember what you called it originally, as it does not offer any guidance to allow easy update.
