You plan on downgrading to the 12400f? Then why would you get this CPU in the first place?
What graphics card are you planning to run and which Windows OS version? Because you realize the 12400f does NOT have integrated graphics like the 12700, and other models that don't end in "f", right?
How much memory and of what speed are you planning to run? How many DIMMs? 2 or 4?
What power supply model are you going to be running?
These are all questions that matter when choosing a motherboard because they are definitely NOT all of the same quality, performance or even compatibility as each other. Regardless of chipset family.
