Ehm, that's doesn't look like a Debian system, but like an Ubuntu.

Please read what's written. One size is the download size (the size of
the .deb, which uses compression), one is the size on disk of the
unpacked and installed package.

No, it ate half of your temporary file system in RAM. No disk
involved.

You've set Dir::Cache explicitly to /tmp/, so it uses that. I don't
see anything wrong here.
And those files are the very same cache that the root user has in
/var/cache/apt/. It's not even aptitude-specific. It's apt's cache
which gets regenerated rather often and usually uses up between 20 and
maybe 100 MB depending on the amount of APT repos in your
/etc/apt/sources.list, if deb-src lines are present in there, too, and
the amount of packages in these repos.

Sure. You told aptitude to everything to _install_ a package except
doing the installation in the end. And so did aptitude.
Why didn't you just use just the subcommand "download"?
→ aptitude download libbest-perl
Executing 'apt download libbest-perl'
Get:1 https://debian.ethz.ch/debian sid/main amd64 libbest-perl all
0.15-1 [15.8 kB]
Fetched 15.8 kB in 0s (250 kB/s)

Then why the hell add additional complexity which does not do what you
think it does? You have so many well documented choices to do so:
* apt download
* aptitude download (a wrapper around the latter)
* apt-get download
* dget
* ...

Yes. Not our problem.

Then why didn't you use the Debian example to report a bug against Debian?

Not necessary IMHO. First hit for "download" in aptitude(8) is:
aptitude [<options>...] {build-dep | build-depends | changelog |
download | forbid-version
Hence closing. Not a bug.
