I have just upgraded from Fedora-35 to Fedora-36 using dnf system- upgrade. The upgrade appeared to go without problems, but the system has been extremely slow since the upgrade -- programs take a long time to start or respond, delays in typing, etc. There seems to be a great deal of CPU and disk activity for no apparent reason

Run a top (top, htop, itop, etc.) to see what is using so much cpu. Run iotop to see what is using a lot of disk io. Look in journalctl at both the boot logs, to see if there were problems initializing, and at the latest additions to see if there is something complaining incessantly about a problem.
For lack of a better idea, I decided to reinstall my system: I built installation media using Fedora Media Writer and started a re- installation process. However the Fedora installer for KDE thinks my system is BIOS based, while in fact it is UEFI based; so it wants me to create a biosboot partition at sector 0 of the drive.

An install will only use UEFI if it is booted in UEFI mode. The fact it won't install in UEFI mode is highly suggestive that you are not actually using UEFI when you boot the install media. Get into the BIOS, and make sure that you are booting the install medium in UEFI.
You could also try another boot medium. I like to use the bare bones system cd, as it is small, and so simpler. I think it is called server on the Fedora download pages. That is what I am basing the above observation on, as it will not install in UEFI if it is not booted in UEFI.
From the system specs you provided, you should not be having any problems with responsiveness.
