Generally, you can use prop-rep methods, but some of the considerations in choosing which method shift a bit. Complex ballots are not as much of a problem as in bigger prop-rep situations, while premature elimination isn’t as big a problem as in single winner. Thus, for off-the-shelf methods, STV or EPH are pretty good in those cases. If I were to design a method for a specific case, I could probably do better, but it might not be worth it.
