I’m also not so fussed about weight. My saddle bag has -
Tube
Multitool (mine includes chain breaker)
Tyre levers (plastic)
Quick link
Couple of zip ties
And...two things that no one seems to carry...
One pair nitrile gloves
One sealed single wet wipe
(I hate greasy/dirty hands on my grips!)
I have a small high pressure pump strapped to frame.
At one stage, I used to carry an emergency space blanket (folded down to size of a half-sized permanent marker), but over the years, I’ve figured that I’m never that far from shelter, a shop, a farm house etc.
