Hi,
I'd like to reject emails that are not sent from a valid DKIM-enabled
sender. Previously, I enabled similar checks for SPF, reverse DNS,
sender verification, and even more, and found that there are numerous
sources on the web that help. But for DKIM, I could not really find
anything useful,

Do not do that. Failed DKIM is the same as no DKIM at all (by RFC) and
here is a lot reasons why legitimate email can have broken
