After considerable thinking about your request, I've come up with a
recommended election method for your situation.
The method has these advantages:
* Uses open-source software that is already available.
* Does not require any modification of the software.
* Provides proportional results for the five seats.
* Provides quota-based representation for women -- which, as I
understand it, you specified as requiring a woman in one of the top two
positions, and another woman in the next three positions.
* Is very resistant to strategic voting.
* Produces better representation compared to using STV (single
transferable vote).
The method consists of running VoteFair _representation_ ranking
calculations. Five levels of representation would be requested. As a
part of that calculation, VoteFair _popularity_ ranking results are also
calculated for all twenty or thirty candidates.
Although what I'm going to say may be a bit offtopic, I think I should
say it. I think it could be useful to quantify exactly what is meant by
quoted-in proportionality in the sense that the Czech Green Party
desires it. Then one may make a "quota proportionality criterion" and
design methods from the ground up that pass it.
It's very easy to otherwise come up with something that sounds nice
(hey, I did it myself) but that doesn't pass the idea of quota
proportionality as envisioned.
(Also, speaking of criteria: if I had enough time, I would try to find a
monotone variant of Schulze STV. I think one can make monotone
Droop-proportional multiwinner methods, since I made a Bucklin hack that
seemed to be both monotone and Droop-proportional. However, I have no
mathematical proof that the method obeys both criteria.)
