For a historical example:
On 22 November 1968, a DC-8 flying from Tokyo-Haneda to San Francisco accidentally undershot the runway at its destination by quite a bit and ended up in San Francisco Bay.

The 107 passengers and crew on board, none of whom were injured, evacuated the aircraft into five of the aircraft's seven liferafts:
Two liferafts were stowed in ceiling compartments over the aisle adjacent to rows 1 and 2.
Five 25-man liferafts were stowed in ceiling compartments in the aft passenger compartment. Three of these were in the area of the over-wing exits over the aisle seats at rows 12 and 14 and two in tandem were over the aisle at row 3l, the last row of seats, and just aft of this row. [Page 22 of the report, numbered as page 20.]
The two forward stowed liferafts were removed from their compartments. One was launched at the main door and the other was launched through the forward service door.
Two of the four rafts stowed in the over-wing area were utilized. One was launched from each wing. One of the rafts stowed in the aft portion of the fuselage was carried forward and launched over the right wing. All of the wing-launched rafts were deployed from the leading edge of the wing.
Although some of the tourist-class passengers evacuated from the forward doors, generally the first- class entered the two forward rafts, while the tourist passengers entered the raft at the left wing and one of the rafts at the right wing. The remaining raft on the right wing was occupied by the captain and JAL employees.
From the passenger and crew statements, it was estimated that 29 passengers (no crewmembers) evacuated through the forward left door; 16 persons, including the flight engineer, navigator, and a stewardess, evacuated through the forward service door; 28 evacuated from the left wing, including at least two stewardesses and three JAL male employees; 25, including the first officer and a stewardess, occupied the inboard raft on the right wing; and nine, including the captain, purser, and two stewardesses, occupied the outboard raft on the right wing. [Pages 23-24 (numbered as 21-22).]
(My emphasis, and the passengers and crewmembers who evacuated from the forward doors and the left wing also disembarked into rafts; it's just that each forward door [and the left wing] had just one raft each, so, for these exits, there was no need to distinguish who got into what raft, unlike the situation with the right wing.)
- Commercial jet flight: a scheduled JAL flight in a DC-8-62. Check.
- After 1945: occurred in November 1968. Check.
- Carrying paying passengers: 96 of them. Check.
- Minimum aircraft capacity 50 persons or more: there were 107 on board, including 96 passengers, and Wikipedia gives the maximum passenger capacity of a DC-8-62 as 189. Check.
- Raft(s) stored inside cabin pre-deployment: in ceiling compartments above the aisle (similar to those in the 737 in the photo in the OP's question). Check.
- Raft(s) actually designed, and put there, for that purpose: see previous bulletpoint. Check.
- Raft(s) worked as intended: well, everyone on board evacuated into the rafts uninjured, and nobody drowned. Check.
