Does supporting the nvenc 4:4:4 format even have any advantage? Does it
support encoding something non-4:2:0? If not, then the first option is

With sufficiently new hardware it does. It will output h.264 or hevc
with 4:4:4 by default if given a 4:4:4 input format.
I noted that as an additional disadvantage of the current logic. It'll
produce
4:4:4 output for >10bit 4:2:0 input, which is unnecessarily incompatible
with the wider world.
