> …when switching Lumen (UE5's realtime global illumination feature) to the lowest setting, this results in completely flat lighting for the vegetation but is needed to get an acceptable base frame rate (it doesn't solve the random stuttering though).

This also happens to many other UE5 games like S.T.A.L.K.E.R. 2 where they try to push the graphics envelope with expensive techniques and most people without expensive hardware have to turn the settings way down (even use things like upscaling and framegen which further makes the experience a bit worse, at least when the starting point is very bad and you have to use them as a crutch), often making these modern games look worse than something a decade old.

Whatever UE5 is doing (or rather, how so many developers choose to use it) is a mistake now and might be less of a mistake in 5-10 years when the hardware advances further and becomes more accessible. Right now it feels like a ploy by the Big GPU to force people to upgrade to overpriced hardware if they want to enjoy any of these games; or rather, sillyness aside, is an attempt by studios to save resources by making the artists spend less time on faking and optimizing effects and detail that can just be brute forced by the engine.

In contrast, most big CryEngine and idTech games run great even on mid range hardware and still look great.
