I’m getting ready to sell my 2021 iMac 24” M1. In doing research I keep seeing ads for iMacs with 4 USB ports, but mine only has 2 USB-C ports and nothing more. I haven’t seen any other iMac M1 with only 2 ports. Have I got the only 2 port system there is?

The entry level ($1299) iMac M1 2021 does in fact have only the two Thunderbolt/USB-3 ports. These should be marked by a thunderbolt icon.
Two other tiers of that iMac have an additional pair of USB 3 ports.

Apple has had two- and four-port models for a while, including with the current M4 two- and four-port models.
In your 2021 case, the gigabit Ethernet was optional with the two-port, and included with the four-port model.
