might be a bit heavy for this, but ive been having fun with nextcloud… its caldav based, i think. ive got it syncin with outlook calendars and the mobile client seems to throw shit in my face as needed
havent really messed with the contact stuff though

and yeah, pulling an integral, configured component and expecting it to just run fine seems kinda… psychotic.
