I typically use 'yum upgrade' because I just want to make sure I have the
latest patches. Often, I will do 'yum --enablerepo=\* clean all' to ensure
I don't have stale metadata, first.
I also occasionally use 'yum distro-sync' to drop orphaned packages, and
rely heavily on plugins like "protectbase", "keys", "show-leaves",
"remove-with-leaves", and "fastestmirror".

I also sometimes use 'yum localinstall' to install specific packages with a
URL or filename (to install RPMfusion repos, for example), because I don't
want to see warnings about rpmdb modified outside of yum with using rpm

I frequently use 'yum list installed' to and wildcard patterns to the list
command to search for specific packages (because search tends to show
32-bit duplicates and I don't typically need the description, just the
package name, when searching).

In cloud init scripts I frequently use '-y' and '--skip-broken' to install
or upgrade specific sets of packages, because these scripts run
non-interactively and I want to upgrade some things even when I can't
upgrade everything. In my normal workstation environment, I typically only
run yum manually from the command-line and don't need these.

I have not yet tried dnf at all.
