RCV is simple and you should support it or something like it if you are a proponent of Democracy:

Did a candidate get a majority (>50%)?

Yes: They win, the election is over.

No: The candidate who got the least 1st round votes has their supporters 2nd choice votes added on to their supporter's second choice candidate.

Does a candidate have a majority now?

Yes: They win, the election is over.

No: Repeat with those who had the least votes in subsequent 'rounds' until there is someone who has a majority.

Why ranked choice over approval voting?

Approval voting appears to avoid the biggest pitfalls of FTPT, it's easy to explain (no run-off, etc) so fewer spoiled ballots (IRV results in more spoiled ballots by a large margin), and the physical ballot doesn't have to change (voter simply allowed to fill in the bubble for more than one option).

It's simply the one we had a referendum for lol.

I would guess that changing plurality to "most approved" would have brought up other constitutional questions too.
