No, you don't necessarily need a modem for fiber if your service provider offers a direct connection.

Do you have their 2Gbit plan available, or is there another option? What options do they currently offer? If you possess a 2Gbit plan, based on what I found, with a 10Gbit MMF SFP and a suitable device, you should be able to operate your own gear after the transition: https://www.xfinity.com/support/articles...ver-1-gbps.
Note: If you don’t have the 2Gbps plan, it’s likely you’re using coaxial service. I wasn’t able to locate any fiber plans from xFinity that indicate anything under 2Gbps, and the higher-speed options are typically coax-based.
The ISP needs to provide the equipment. It’s used to get you connected to the network if you have Fiber. Are you confident you have Fiber? Since Gigabit Pro isn’t inexpensive, it’s the only fiber option they provide. Regarding Gigabit Pro, I’ve learned the Media Converter supports a 1 Gbps Ethernet and a 10 Gbps SFP port. If you mean Gigabit through coaxial cable, you’d just need a Docsis 3.1 modem, which can be purchased and used on the Xfinity network.
