In my case I learned all these lessons after a lot of trial-and-error (same for SMTP servers hosted on residential dynamic IP subnets), and I'm currently running it on my Linode VPS.
All green with DMARC/DKIM, all green from Spamhaus, Google usually accepts my emails without complaining, but the main offender is now Microsoft.
And after a lot of (mostly pointless) correspondence with their customer service and reading a lot of similar experience online, I think that they just don't like SMTP servers hosted on VPS subnets like Linode...
