I've setup a SPF, DKIM and DMARC record for my mail. I ensured it
looks pretty good with a mail tester (mail-tester.com if you're
interested). The thing looked really good.

At the time of writing this small email, I haven't had any problem
with Gmail rejecting my emails for any obscure reasons or any mail
providers thanks to my ISP relaying my emails :p

[nonsense follows:]

I believe gmail has some magic algorithms, so if some people have you in their address books for example, you're far less likely to be messed with, etc.
Tho pretty sure proper dkim and whole shebang together, would also make it unlikely you're ignored/viewed as spam (as long as it's all proper and old enough/not freshly made, of course)...
of course, they might also be flagging residential IPs, or specific TLDs or such as having higher risk (like .xyz vs .com), which is unrelated story...
(also not too unlikely they prefer stuff from domains ranked OK in their search and/or stuff like mail.example.net over mymail.example.domain.org or "you must be x months old domain and stuff to be taken seriously" etc...)

[/nonsense]

on one hand, they do half these things to fight spam...
on the other hand, well, there are always alternative big mail places, which are just as good/bad otherwise, like yahoo and mail.com (mail.com has SOOOO MANY domains to choose from when creating account...) and microsoft's one (yes you can still create @hotmail.com address, pretty sure) ;p

I like to keep a mail.com address reserved for stuff I don't want to be associated with me (including one-off account registrations and things likely to be spam, etc, as it's not blacklisted unlike nearly all temp mail providers ;)
