APA 7th edition default for pages?

As there are no APA 7th Edition templates included with Pages, you have two choices:

1. Use Micrsoft Word and a specific APA 7th edition template for Word, and its 7th Edition Bibliographic template.
2. Painstakingly create your own versions from a blank template in Pages, or import the Word APA 7th Edition template(s) and hope they translate accurately without Word dependencies messing up the import and fonts.

Templates for Word can be found here and here.
