Frame Rate on 5D4

I normally shoot at 23.98 (on 5D3) but now with extra options on 5d4, just wondering what frame rate I should choose so that its available to wide range of buyers

Full HD - 1920x1080

59.94fps
29.97fps
23.98fps

Also, there is an item called 24.00p which is by default disabled.. Should i just leave it as it is ?

I shoot 29.97 on the 5D MK IV, III, II , 1DX MK II, Sony 4K .... oh heck on all of them. See no added value shooting any other frame rate. If the end producer wants a "jerky" look they can slow it down easier than trying to speed it up.
