Agree, I don't think it makes much sense to split things into many small
pieces.

I'd say yes by default, but being able to remove it might be useful
(kernel-netfilter subpackage)?

I'm personally using NFS for host/guest filesystem sharing, so I'd vote
yes.

I think no. That's a host side thing and this is about the guest
kernel, right?

Depends on what is targeted. Strictly cloud? Or also someone running
Fedora as a guest in virt-manager / boxes?
I'd tend to include drivers for pretty much everything qemu can emulate.

spice guest agent uses this.

bluetooth+wireless are not needed, dunno why they are loaded.

For the qemu HDA soundcard. Should be included if desktop usecase
should be covered too.

gpu driver. There are also cirrus + bochs-drm for qemu.
vmware vga has a drm driver too. They should be included.

IDE. Needed. Qemu can emulate AHCI too, should be included (but I
think that is =y anyway).
Qemu can emulate a bunch of SCSI HBAs. Don't think we need the drivers
for them (except virtio-scsi). vmware emulates SCSI HBAs too. pvscsi
should be included. Dunno about the older ones, there was for example
some buslogic emulation in older vmware workstation versions ...
USB: Qemu can also emulate uhci + ehci + xhci, should be included. Also
usb-storage and generic hid support (for the usb tablet). IIRC most of
this is =y anyway.
NIC: e1000, rtl8139 (qemu), tulip (hyperv), dunno about vmware. qemu
can also emulate a bunch of other nics such as ne2k, but I think those
are not relevant in practice and not needed.
Of course all paravirtual drivers should be included too, i.e.
* all virtio (for qemu)
* all xen frontend (for xen, the backend drivers are for the host
side and are not needed in the guest).
* all hyperv (for hyperv)
HTH,
