Windows 11 and EndeavourOS dual boot - "install alongside" option

When I select the partition that I want to install Linux on, what mount point should I select?

In the installer you would need to:

• point it to the EFI System Partition >> mount point /boot/efi and flag it as boot (OBS! Not format)

• point it to the free space >> mount point / and format EXT4

Do I need to have a swap partition (I have 32GB RAM and have never used it all up)? If so, how can I create it, and how big should it be?

If you are not planning to use hibernation, you would not need a separate swap device.
In the case you would change your mind later on, this can always be done post-install as well.
There are several options. One is zram which would setup a compressed swap space in RAM whenever there is a need to swap out some pages out of RAM.

Can I leave Windows partition as NTFS, and Install Linux as ext4? Will they be compatible with each other?

You should leave Windows partition as is. You could access it from your Linux system. If you need to write to that partition, you would need to make sure to shutdown your Windows properly. That is no fast startup and hibernation in Windows.
