Would this work for optimum 300mbps plan?

Check with the ISP but it should if they support DOCSIS 3.0. Max throughput this modem can handle is 400Mbps.

This ethernet cable is suitable for it: https://www.amazon.com/gp/product/b06xhdt44g

That's a long cable, and I'd recommend a much shorter connection to a router, but it will work.

do I need a router or just a switch will work for Ethernet connections to other computers?

You need a router unless your provider can can give you more IP addresses. Typically, you want to use a router both to allow multiple systems to connect, and to provide added security, since most routers provide firewall functionality.
