Need advice on engine swap ( MB C180, w202)

[MBC180]

Hello All and happy Easter holiday

Have a Mercedes C180 w202, 1997 that now has a 1.8 lt petrol engine.
have come to the part where I would like to change engine as the engine has gone 420000 km, and it has maybe seen it last days soon, and to get the engine overhauled would cost some so then thought to get a bigger engine for the car.

Have been looking on getting C32 or C43 engine and wonder if any have some expertise witch of the engine that would fit best in a C180?
Also got an offer to buy a Mercedes m119 motor from R129 500SL.

So any advice would be nice of what I can put in as an engine, without to much rebuilding of the engine room.
