Why do you think it should be hd0f ?
Does the kernel show wedge names and attach dk* devices befor you get
the root device prompt?

The emulation probably did not pass throught the proper physical sector size
so alignment was off when creating the additional NetBSD partitions.
I would fix that first before proceeding, ignoring it might have performance
and disk/ssd lifetime downsides. The GPT output requested above should
help with that.
I would do such multi-boot installations (assuming you are using GPT
partitioning) in a multi-step aproach:
1) manually create an ESP (EFI) partition, a swap partition and a main
NetBSD partition. You can do that e.g. by booting the installer,
drop to the shell, identify the disk you are targetting (by
dmesg | more, identifying e.g. wd0 or ld0 as the target, and then
verifying it has the proper partitions for the other OSes by
"gpt show wd0").
a) use "gpt add -t efi -a 2m -s 64m wd0" to add
the ESP partition, note what "dk" device it tells you it created
and then format that with something like "newfs_msdos /dev/rdk5",
mount it: "mount -t msdos /dev/dk5 /targetroot" and copy the
UEFI bootloader there:
mkdir -p /targetroot/EFI/BOOT
cp /usr/mdec/*.efi /targetroot/EFI/BOOT
and unmount it again "umount /targetroot".
b) add a swap partition of whatever size you need, like:
gpt add -t swap -a 2m -s 64g wd0
c) add a main NetBSD partition of whatever size you like:
gpt add -t ffs -a 2m -s 64g wd0
d) verify everything looks good by: gtp show wd0
2) return to the installer (by exiting the shell, e.g. with ^d),
start installation and select the pre-exiting wedge you created
in step 1c as the install target.
The installer will find the swap partition created in step 1b and
offer to use that.
