Proportional Representation is what you need for multi-seat bodies like parliament. It’s absolutely the best method for such bodies, imo. For single seat elections, proportional doesn’t work as their are no proportions for a single seat and generally you don’t want to just vote for party for such roles, but individuals themselves. You’ll need something like Ranked Choice or (my preference) Approval voting for those seats to avoid the two party inevitability.
