IIRC it’s been mathematically proven that no single-member electoral system can be perfect. If it wins in one area it fails in another.
My preferred system is to use a standard ranked ballot, count it using IRV until every candidate has above 20% and then switch to ranked pairs (so there are no spoilers, but the daylight savings party doesn’t end up winning by default).
Also, the thing you’re likely thinking of is Arrow’s Impossibility Theorem, which only really applies to Ordinal (Ranked) systems. Cardinal (Rated) systems don’t suffer from the failings of Arrow’s Theorem.
I’m not really a fan of the multi-member district, I’d rather just shrink the size of the district until they are more homogonous, and then just send one rep from dozens or hundreds more districts.

Yeah, just avoid IRV completely.

Local democracy is more democratic after all.
