Mate my water pump just dropped it’s gits on my WB. It was new when I rebuilt the engine less than 100000km ago. The fan hit the radiator and I nearly cooked it. There was no bearing noise that I noticed. I assume you have run coolant/inhibitor.
As for oil pumps, it’s common for cam lobes to wear off due to low oil pressure at low revs. Usually cars that do lots of slow, short running around town. I reckon that’s what most restored cars do. As far as I know though, gear pumps either work or they don’t. If you change your oil regularly and use quality filters they should be good for a long time.
