I might just be confused (again).
what ever you do try this link https://dmarcian.com/spf-survey/ do NOT include domain with active A AAAA MXinstaed create _spf.example.net and use it for include, so the _spf is not pointing to A AAAA MX, this will create duouble listning with can hide permerrors
if you later do setup dmarc, and see pass from your own ips you are done, the above link have being very helpfull to me
