As already stated essentially unless 90% of your journeys are 20 miles return or less a PHEV won’t do you any good. They sound all cheap to run & good for the environment etc but when you look at it they’re really a bit of a white elephant, that’s not to say a waste of time for all but you have to be very careful not to get suckered in.
I think the vast majority would be better off with a standard good economy ice esp for occasional towing.
Good luck with your choice
PS EVs can tow technically & physically but manufacturers just don’t rate them for it, lots in Australia use them for towing due to their boars, jet skis etc
