At 10-11 years on my 2007 XS 5-spd, about 150,000 km, I had the clutch, and (separately) the timing belt (plus all the bits that go with it like water pump) done. I've done that kind of stuff myself on simpler cars (older Civic) but had a shop do these on the Forester. Other than that, I changed the two belts on the front of the engine. One does the alternator, one does the hydraulic power steering and a/c compressor, I think. It was tight, and I had to use a 1/4" ratchet with long pipe on it, and shave down a 10 mm socket with a grinder so it would fit. If i didn't do that, I'd have had to take the radiator out I think. I was getting shuddering when demanding a lot from the power steering, and I suspected the belt, and I looked around and found that the belt was loose. When tightening the belt I noticed that it should be changed, so I changed both of those belts. For the clutch, it was fine and then stuff didn't work any more, like one day the pedal didn't come back up. I had to screw around with it, playing with the pedal, shifter, etc to limp the car home, and then next day I limped it to the shop, and the throwout bearing was toast. On all my cars, the throwout bearing usually fails before the friction material is worn out. Many years ago on the Civic I used to hold the clutch pedal down at red lights etc, but I didn't do that on the Forester. (It's not good to do.)
Other than that, the clutch on the a/c compressor was worn and so the compressor wasn't getting spun. I had planned on doing that job with the shims, but it was fall and I postponed it. The car was a little foggier that winter. I ended up trading the car in when I found that the 2018 was the last year Subaru was going to have the XT. I got my 2018 XT in ... April 2018 I think, and I never did the a/c job on that 2007.
The other stuff I did that was more involved was: I had to change the power lock actuator on the driver's door, and I changed the crappy stock stereo to an aftermarket one. The stereo was the old 1-DIN style, just a simple replacement. Everything else was just oil changes and "fix it if it's broke." Let me say that I love the oil filter on the top of the engine on the 2018. On the 2007 I had to stick my arm up a long tunnel to unscrew the filter, and when the filter came off, oil coated my arm and surrounding car bits. Not fun.
