Is it a computer-only product? or is it for consoles / other platforms too? If for console too, then trying to get and maintain over 60 FPS is almost pointless because the current generation of consoles lack the capacity to render more than 60 FPS, except for perhaps the Pro versions (PS4 Pro, etc). And for computers, lots of computers are still in the 8-16 GB RAM / 2-3 GHz CPU range, and do not have dedicated graphics cards. Even ones with dedicated GPUs are restricted to not sharing some resources, and the refresh rate of the monitor, apparently, must be 120 MHz to attain 120 FPS anyway. The main purpose of maintaining higher FPS is to synchronize rendering with the refresh rate of the display, thus removing stutters, stops, and certain kinds of lag. The FPS is also restricted by the type of HDMI in use, 1.4 or 2.0, and the resolution, 1920x1080p or higher or lower for some computers. So, optimizing to a certain FPS isn’t the answer alone. It’s going to require optimizing for particular computer specs, particular platforms, and even particular TV setups. Optimizing for faster and less problematic use of Unreal Engine is different from optimizing for platform/device scalability.
