My 2013 iMac doesn’t wake without a WiFi connection.
Whenever I leave the house and turn off my WiFi and come back to it later, my iMac won’t wake up, how and why does it do this? (I'm on Catalina 10.15.3)

Why do you turn it off? I always leave mine turned on and put the computer to sleep. You might try Downloading and Installing the macOS Catalina 10.15.3 Combo Update. See if that fixes things. Also, see If your Mac doesn't sleep or wake when expected and Tackling sleep and wake problems – The Eclectic Light Company.
If you still haven't been able to fix it:
Possible Fix for Wake-Sleep Problem
You should try each, one at a time, then test to see if the problem is fixed before going on to the next.
If your wake problem ceases in Safe Modethen read the article about what safe mode disables and look there for a possible culprit. If the wake problem ceases in the new user account then the problem is located in your Home folder or your third-party applications that are running. Test with only one application. Then add one at a time and test the wake-sleep issue.
