for O365, you don't need SAN certificate, your adfs single hostname cert will work though you have multiple domains

If you wanted to publish Apps with different domain names through your web proxy server, you need cert with app URL FQDN and that must be installed on adfs proxy server
Infact no matter you have app published with same domain name as adfs, still you need to install app URL certificate on web application proxy server
