The +1.1L means that the current level is 1.1L above the minimum (minimum is 5.5L).

Also worth noting that even though the capacity is 6.5L, the system will hold onto about 1L when you drain the oil. So you should only fill 5.5L.

If you completely empty the system (oil radiator etc), you need approximately 7.5 to 8.0 lt.

Mine took 6.5 L when I did rod bearings (completely empty oil pan, and I also emptied the oil cooler since I did the oil cooler lines at the same time). Not a CSL, but those parts are the same.

Is the general preference to keep it near to +1.0 (in particular to help with cooling)?

Since the S54 doesn't have a crank scraper, it's probably better to keep it slightly below the maximum. 0.7ish is what I go for (about 3/4ths the way up the dipstick if you can check that). 1.0 is fine too, but I'd be careful of going above that.
