It may depend on what type of install you want to do. I recently
installed F36 on a new system I had built, where I was putting Windows
Drive C, Ubuntu and Fedora boot partitions on an SSD, had 2 3TB disks
for windows data, a 1TB disk for the rest of Ubuntu and a 3TB disk for
the rest of Fedora. Windows and Ubuntu were installed first. I just
pointed the installer at the partition I wanted Fedora installed in,
which was after configuring the partition as GPT as a Dos partition can
only address 2TB is storage, and told the installer I wanted the
partition on the 3TB drive as "/", and the partition on the ssd as
"/boot". Having done this the installer refused to do the install
because being a UEFI install the installer wanted a mounted UEFI system
partition, so I had to reduce the size of the "/boot" partition to
create a 100MB partition as an EFIOS (I think) partition specified to be
mounted as the installer wanted, and then it proceeded to completion.

All my installs on mixed OS systems have used the existing EFI partition
with Windows or macOS. One thing to check is Windows fast-boot, which
is really hibernation and must be disabled or the system will recover
directly into Windows.
 
As Patrick said, I would expect the automatic installation to set up the
necessary partitions for you, but I don't know for sure as I have never
done an automatic install, I have always specified the layout I wanted
explicitly.

When you install onto a bare disk it does create the partitions. I like to
have a bootable USB drive (currently I'm using a USB-C adapter with
an NVME SSD). for rescue/troubleshooting.
