My GFs use case is a bit weird. She works from home and only occasionally has to do a long drive to her office. She owns a horse and has to go to the stables daily, but it's only a few miles, as would be any local driving for the shops, etc. Usually this would full BEV territory; even her office commute would be no more than about 140 miles a day. But...she also needs to tow a horsebox every so often. For obvious reasons you absolutely don't want to be caught short for range, and can't stop to charge up for long periods with a horse in tow. So I reckon that a PHEV, even with a modest battery-only range of maybe 30 miles or whatever would be ideal - that would be enough for all the daily local driving, could do all the short trips into town without even firing up the engine. But then if she needs to go to the office, that's not a problem, and it would be less worrisome when towing Trotter McLong-face around.
Still looking at options at the moment. I did consider starting a PHEV thread for ideas and discussion but didn't know if it would step on the toes of this thread too much.
