I need link to some very basic parameters of different FPGAs

Total FPGA novice here (software guy). I haven't seen timing information like that listed for any brand of recent FPGA. I think the expectation is that the tool set will be used to get timing info.

On a project I worked on several years ago, the FPGA team coded what they knew was the most time critical logic and entered the time requirements in the tools. They then tried to meet timing with several different brands and families of FPGA dev tools. Once they knew what would work they looked at size, memory, transceivers etc. Mgt then negotiated with vendors for quantity prices. We then purchased dev boards for an FPGA in the brand selected that was one size bigger than what we thought we needed and used that. Sometimes we could drop down a size in the end and sometimes not.
