I would prefer solution 1 or 2, which use VA-API and have the broader
support
(https://wiki.archlinux.org/index.php/Hardware_video_acceleration#Application_support).
Haven’t tried an AMD GPU, but it should be working fine nowadays. So at
this point this is mostly a question of which CPU you want. And
currently AMD ones seems to be quite above Intel solutions. ;)

3 would work too, but as Maxime pointed out relies on NVDEC, which might
not be supported everywhere and of course relies on Nvidia proprietary
driver (which, depending on the lifetime expectancy for your new PC,
could become an issue at some point —e.g. when the driver version for
your GPU won’t support newer X/Wayland/whatever display server will be
used by then).
