ExFAT is not limited to a 4GB maximum file size. It just has more than 4GB in the file.

I guess 4GB seemed like a reasonable limit when FAT32 was designed.

Most likely FAT32 has a 32bit number for file size and ExFAT presumably has either a 64bit one or stores file size in some format other than bytes.

FAT32 was always seen as stop-gap measure for low-end consumer hardware when introduced in 1996; NTFS was introduced 3 years prior to handle terabyte-scale data for enterprise users.

Correct.
