Hi,
You can use SP Page Builder Pro with any Joomla template in theory. But, SPPB better suits with Helix Ultimate Framework as well as template. So yes, you can install Helix Ultimate from here:
https://www.joomshaper.com/joomla-templates/helixultimate
If you have any confusion about the template pack and the quickstart pack then you may have a look into the following documentation section:
https://www.joomshaper.com/documentation/helix-framework/introduction#template-vs-quickstart
In general, Helix Ultimate comes with SPPB lite, so you will need to install SPPB pro there after you have install the template. Then you will get all the layouts right within your SPPB.
Moreover, SP Page Builder works with contents that appears within the conponent area, while with Helix you can control the contents, that are outside of the component area(such as header, footer, etc).
If there is anything left that you need to know about or you have confusion, kindly do let me know. I will try to help you out.
Best regards,
