That's kinda the entire point. One of the (many) metrics for voting systems is called Voter Satisfaction Efficiency (VSE). This is basically a global L2 distance from each voter to each candidate. To maximize VSE we want to minimize that distance. In other words, we want winning candidates to be most representative of a population's opinions and values. You can see a comparison of different systems here[0]. Note that there are other criteria that matter, but there are plenty of methods that have high VSE and the other criteria we want. Also note that the spread in different types of strategies represents the method's vulnerability to manipulation. If a strategy still yields a high VSE then it is not an effective strategy.

If I'm not mistaken this link is exactly what I am describing. It simulates how close the winning candidate is to voters based on how people would vote. But it explicitly doesnt simulate how candidates would shift due to changing incentives.

In other words - it treats elections as a one side game where voters pick strategy (voting methods/preferences) and the candidates are stable. But it is a two-sided game where politicians change opinions/policies based on system as well.

That is a hard thing to capture, but strategy is a decent way to approximate it. I do think this is fair criticism for what it is worth, but I don't think anyone has been able to create an accurate model for this (for any voting system) and I'm not sure you can accurately model this tbh.
