Moving in to 3-floor building, landlord provides the internet, doesn't let us run LAN cables between the floors.

I work in an SMB with ~100 employees and we got three offices with one of them being the main office where all our servers sit at (emails, AD, file serers etc.)

Each of the secondary offices is connected with its own subnet, through a VPN tunnel to the main office and we only got seperate phone system servers and WSUSs in each of them, nothing else.

We are now moving one of the secondary offices to a new building which will be 3 floors big. The floors are not wired to see each other but they have two cables each, going to a data cabinnet on the ground floor. These cables are being used by the landlord to provide an internet connection to each floor (one cable for internet and one backup). Our lease contract is for 750Mbps internet spread at a fixed ratio of our liking for each floor.

The problem I see here is that each floor has to be treated as a whole office, requiring us to install a router, a WSUS server, a phone system server and a different subnet for the new VPN tunnel to the main office ... for each floor.

I've proposed that we should use one of the two cables from each floor, to install a switch on the landlord's data cabinet, right before their router, to create a link between the floors. Then we can use one of the backup cables on one floor to connect it to the landlor's router for internet access.

Our company doesn't mind installing seperate servers/routers on each floor but I think it adds unnecessary complexity.

What do you guys think? Do you see any other selling points here?
