If you're going to have a large multi-member district with proportional representation, it's not essential to use ranked-choice voting - you can get a reasonable result just by having people vote once for the ticket of candidates they prefer, then allocating the seats proportionally.

That said, ranked-choice voting in large multi-member districts is certainly possible: It is usual to require voters to rank only as many candidates as there are vacancies, though they can number more if they wish to (consequently they don't need to understand the detailed policy positions of the minor candidates that have no realistic chance of election). Voters in such systems tend to firstly order the parties based on the policy positions of those parties, then order the candidates within those parties if they have a strong opinion of the relative merits of those candidates.

Here's an example of a media summary of the candidates running in such an election: https://www.abc.net.au/news/2019-05-17/federal-election-2019...
