Had it been a long time since the last update?
Or rather, if the list of updated packages is not long, you might think about looking (e.g., in the upstream sites) for information about those updates.
Otherwise, I guess you have done more than one reboot?
I think linux-modules-cleanup.service only appears on the first reboot after a new kernel. You might see if the situation improves with a new reboot.
Otherwise, maybe I would try changing kernel, such as switching to linux-lts for a while.
NetworkManager-wait-online.service could be probably disabled, see e.g. a relevant discussion here, but it's not that big time...
