I did this as a small-scale experiment/proof-of-concept earlier this year in my 2 br apartment, preparing for wiring for 10G (and possibly beyond as the years pass) when I move into my house later this.
I went with singlemode fiber. Don't really see the point of multimode. At all. After doing some research I am not sure who it is made for.
Sure, the BiDi SFP+ modules are a bit more expensive but not overly so.
The fiber is cheaper.
It's easier to splice/use field assembly connectors if needed.
Much easier to hide the cables. If you go with 0.9 mm you can even hide it in nooks and crannies under door trim etc.
It is future proof. SMF will always be supported.
Now the only problem is that the Mikrotik CRS routers I want to get are either out of stock or have insanely inflated prices. Seems to still be affected by component shortages. I already have a couple of CRS305 and some CCS610, but I'm going to need more of those now plus a CRS309 to scale it all up.
I think back 15 years or so ago, multimode fibre and optics were quite substantially cheaper. Given that you could still get several hundred metres to over a kilometer with the slower speeds available at the time, it probably was worthwhile. But by the time I got into fibre stuff SMF was not much more expensive, so I've always just used it by default.
