Hello devil,
i tried it. The numbers are not directly comparable, as i had to install 25 packages
(apt + virtualbox-guest*, xserver-xorg).

After this operation, 483 MB of additional disk space will be used.

Abort.
So the result is similar to the solution of aspcud. But even the old apt-get can do this:
apt-get upgrade --with-new-pkgs
726 upgraded, 112 newly installed, 0 to remove and 12 not upgraded.
None of the tools prints reasons for its decisions as clearly as aptitudes interactive resolver.
Sadly its first suggestion isn't the best solution, so you need to press n to iterate through the solutions:
aptitude dist-upgrade
-- lists of 852 packages omitted --
738 packages upgraded, 116 newly installed, 0 to remove and 0 not upgraded.
Need to get 493 MB/493 MB of archives. After unpacking 484 MB will be used.

Abandoning all efforts to resolve these dependencies.
Abort.
Obviously there is no warranty that you find a nice solution as quickly as in this example.
Iterating through tens or hundreds of possible solutions usually is not successful.
Better reduce the number possiblities by setting libqtxdg0 on hold and then try again.
The idea is: Let some tools try to find a valid solution but dont break my own brain with tons of output to read.
Different situations need different algorithms, so it's good to have several tools to choose from.
This complexity is the reason for the introduction of aspcud, packup and other alternative solvers.
Oops, now i mentioned packup. Are you ready to try it? Who is the first to give feedback?
Wow, what a lengthy thread, you get bonus points for reading to the end!
Thanks for your interest.
greetings
