We have a local ISP [0] that builds FTTB, usually with 1000BASE-T to the individual units. Sometimes, if laying STP cable isn't easy and the customers don't need anything more than VDSL can provide, they replace the (L3?) switch in the basement with a DSLAM, but I think those are quite a bit more expensive than a switch with 10G SPF uplink and 1000BASE-T downlink (possibly aggregating a few 10G uplinks for large buildings, I'd guess). (Germans tend to deploy shielded cable, seems to have something to do with both unifying deployments between known noisy RF-environments/eliminating problems with noisy RF-environments up front and with (electrical?) codes that don't discriminate against shielded twisted pair cabling.) If you pay for the additional setup, they're happy to provide 10G/2G or even 10G/10G for 199/399 EUR/month. That apparently requires you to provide singlemode wiring from the basement to the units, but to be honest, that's rarely hard to do, considering them being available with coatings that are allowed to be in most low-flammability zones like stairways, quite thin (so it's easy to hide the complete trunk behind a baseboard or along doorframes (if you can slightly round their corners to conform to the bending radius you'll need to adhere to for the many bends you'll have when snaking up a stairwell)), and non-conducting, so there's no isolation/ground fault/lightning protection to consider. If my street would have gotten dug up just a little further when they did so a few months ago for subsurface electricity and more direct water lines (some buildings, including ours, had their water house mains come from a neighboring building through a meter between their intake meter and the other (e.g. our) building's main cut-off valve/initial fan-out piping. Note, I would have literally dug into my meager savings and bankrolled/installed fiber conduits in accordance with what this ISP would accept/recommend, going from the houses (talking to the communal utility for sharing the wall feed-through, because at reasonable rates that's literally cheaper than buying the part/renting the drill to DIY at all the neighbour's houses that would take my offer of installing it for free) to a connector/hub box or just something that keeps the insides of these pipes clean from dirt and significant moisture ingress (maybe with a slight distribution to blow dried air through from my house's connection, and flow-regulating valves at the other buildings to extract any moisture that will diffuse through the walls, or something like that). Once the street between there and the next conduit where the ISP can easily get fiber to (without digging) would get torn up (happens eventually), I'd make sure that more of this is placed, likely with some larger pipes to stuff further innerducts through for all the other residents on this street (low hundreds in units, about half or so single-unit buildings, half multi-unit buildings, but quite a few build in rows of a couple, so, with appropriate fireproofing, they could share a single house-to-street trench digging). It's not worth it to dig the street up for this alone, but at least the part I'd have placed fiber isn't even paved, it's literally just compressed gravel/dirt mix, and will hopefully get a nice surface sooner or later. It get's rather dangerous to walk when frozen, and because it's not mine I can't use mineral products (salt/sand) to make it safe. Yes, I also offered to fund a coating with crushed basalt, which would restrict maximum torque (the structural integrity/load bearing depends on a certain ratio of downwards vs. horizontal force), but eliminate most issues with water (at times there is no dry footpath that does not involve a >150cm leap from dry bank to dry bank (if you miss-judge, you will jump into a puddle and might slip in the mud)) and thus also some of the ice problems.
