It will prompt you before it removes anything, so you can review the
list of packages to be removed and say "no" if there's anything you
don't approve of there.

"apt upgrade" is a middle ground between "apt-get upgrade" and "apt
full-upgrade"; it will install new packages if needed, but it won't
remove currently-installed packages.

apt certainly can - you're just choosing to use it in a particular
extremely-conservative mode where it refuses to do so.
