I'd support mandatory voting with a required "No Choice" option so people can still exercise their freedom to not choose, but also voter suppression becomes much more difficult.
Might as well add a 'none of the above' option too. If none of the above wins a majority we get a runoff with fresh candidates. Not sure if I remember where I originally heard that idea.
Brazil tried it for a while. https://theglobalamericans.org/2018/08/elections-in-brazil-blank-and-null-votes-are-the-favorite/The Brazilian Constitution of 1988 states that only valid votes count. However, the Electoral Code of 1965 provides for the annulment of elections if there are more than 50 percent of null votes in a majority election (it doesn’t mention abstention). Still, many Brazilian sociologists and political scientists believe the threat of annulling the vote will do little to alter the strategy of the main political parties.
