Except when you install something on linux package manager of your distro is executed as opposed to installer that was made by developer of package you are installing. And you probably install install packages from your distro’s repos, unless you are on Debian of course.
Or you can run package manager as user that usually installs in ~/.local. Or unpack yourself.
Package managers have post install scripts and hooks that would allow you to install a rootkit. Then again they can also just add services on many Linux systems, which can run as root. Just put a systemd unit file in the right place and enable it.
The security advantage of Linux is having trusted repos and using things like FlatPak. System packages being malicious would very much be able to infect a system. Just look at the XZ backdoor for an example.
I believe offline upgrade is also the default on every OS out there, for example gnome software only installs updates offline.
Even if you have to use sudo to upgrade (or journalctl, dmesg, both are sysadmin tasks and not typically done by a normal user), you are still only giving root privileges to these trusted programs distributed by your distro, not some random installers on the internet, unless you are using AUR.
I am genuinely curious what other commands with sudo that you need to run on a daily bases, for tasks that is unrelated to system administration?
Not sure what you’re doing there, but it’s pretty much every other command needs sudo here… Can’t even install updates without it.

The safest way to install update is via offline updates, which don’t need sudo on the user side, but requires a restart. See https://fedoramagazine.org/offline-updates-and-fedora-35/ for a good explanation.
