rpm/dnf only remove packages. Their post scripts usually are incapable of
completing a purge. The NVidia packages are supposed to be provided with
installation instructions that detail how to completely purge. When those are
not
found and followed, what's been happening to you is expected.

Boot initialization involves loading a kernel and initrd (initramfs) via Grub.
Initrds are custom generated normally with installation of every kernel. Adding
proprietary drivers such as NVidia's usually requires that they be re-generated.
These are two of my currently installed ones:
# ls -Ggh /boot/ini*5.1*
-rw------- 1 15M Sep 11 01:43 /boot/initramfs-5.18.19-200.fc36.x86_64.img
-rw------- 1 15M Oct 17 23:26 /boot/initramfs-5.19.15-201.fc36.x86_64.img

I don't know whether your GPU requires it, so go ahead and install it as last
step
after completing other instructions here ready to reboot to test. IIRC, this
will
cause regeneration of at least your current initrd, if not all, so that you need
not do it manually. If it doesn't happen automatically, then run:
dracut -f

Among other problems noted there:
(EE) open /dev/dri/card0: No such file or directory
This is a typical result of failure to load a required kernel module, in your
case, nouveau, which provides KMS needed for X to run competently on NVidia GPUs
using only FOSS software.

This is wrong, the foundational and possibly only problem. Remove both files.
They
prevent loading of the necessary nouveau kernel module.

Because nouveau could not be loaded.

pinxi is the devel version of inxi.
