Cisco Router For Terminating SMF SC Interface

I have a requirement where one of our partner is planning to connect to our datacenter using a dedicated leased line.

As per our partner, they will engage a Leased line vendor for this. This vendor will terminate the leased line ( Single mode fiber -- SC connector) to the Comm room of our Colocation provider.

I have next to nothing knowledge about fiber connectivity and have few questions in this regard.

Q1. If Single mode fiber is terminated at COLO's Comm room in form of SMF SC connector, what kind of cross connect should we request from COlo's comm room to our cabinet. ( SMF / MMF )

Q2. How are these cross connects terminated in cabinet? Do Colo provider use some kind of fiber patch panel or they simply provide a fiber link with SC/LC connectors at the end of it?

Q3. If cross connect needs to be SMF SC then which cisco routers support SMF SC interfaces? Do I need SC-LC patch cable?

(I looked at the various option but could only find the following GLC-LH-SM or GLC-ZX-SM for SMF connectivity. I read about these and found that GLC-LH-SM is used for terminating single mode fiber that spans up to 10 km and GLC-ZX-SM is used for terminating single mode fiber that spans up to 70 km in length. It looks as if both of these support LC connectors. Are these the only two SMF connectivity options? Do I need SC-LC patch cable )

Q4. Our partner only tells us that the terminated link will be terminated using SMF SC. How to figure out if GLC-LH-SM or GLC-ZX-SM is required.
