On that note would you gents recommend single-mode or multimode fiber for buildings?

Single-mode, for sure. More predictable characteristics when you climb
up the capacity scale, e.g., 10Gbps to 40Gbps to 100Gbps.

We use plenty of multi-mode, but only in the data centre, between our
own kit, for racks within the same cage.

Between floors, multi-mode should be good for anywhere from 50m - 300m
(100Gbps all the way down to 1Gbps), but why risk it?
