Most likely not the best form of government.
On one level this is correct and on another completely inaccurate.
Sweden is a parliamentary democracy, with members of the Riskdag elected on a proportional basis. Thus people vote not for a representative for their district, as in US and UK, but for a party, which then doles out its seats by its own criteria. A great many other countries operate on a similar system, which allows minority opinions to have some voice in the government.
We could have a good argument over whether this is a more or less democratic system than ours, but it is certainly not authoritarian in any real sense of the term.
As far as a "limited franchise" goes, Sweden had effective universal suffrage roughly 40 years before the US did.
