Cacti worth trying outdoors in USDA z 8b or higher

Most info supplied by Craig Howe, who grows these in his Northern California garden - around 40” rainfall mainly during winter, annual lows of 20F, often much lower ( recently, 1997/8 it was 13F, around -10C ). High humidity all winter long, many sunny days but sometimes no sun for a couple of weeks.  No guarantees for this lot, however.  Opuntias have been omitted, mainly 'cos there are too many that are worth trying.
