replace CSC early or let it fail one day?

It's a gamble, but I wouldn't put too much into it. Without statistical data and analysis, it truly is a speculation at what mileage that it would fail.

The car is still drivable in medium to no traffic without a clutch. The Synchro Rev Match would make it easier, but it can be done without. It's called, strangely, rev matching. Hard to do in a very heavy to stop-n-go traffic and the route needs to be well-planned to lessen the number of stops. Shifting should be minimized to avoid the chance of wearing the synchronizers too much.

So, basically, when stopped, engine must be turned off. Put the shifter in 1st and start the engine; the car will jerk while the starter is cranking and the engine firing up. Bring engine speed a bit high, around 4-5k, then relax the throttle (do not lift completely) before moving the shifter to Neutral. Zero throttle while shifter is in neutral.

Next gear, I would pick 3rd to minimize shifting, would be engaged while the engine speed is on the way down or, if the Sport mode is engaged, the Synchro Rev Match will put the engine at the correct speed. Slide the shifter into the next gear, there should be little to no resistance when the engine speed and the vehicle speed are matched for that gear. If a downshift is required, slide the shifter into neutral, blip the throttle (or Synchro Rev Match would do it) while gently resting the shifter at the gate of a gear; once revs are matched, the shifter will slide into gear.

When a stop is imminent, reduce speed accordingly in gear. Once engine speed is low enough (I use 1.5k rpm or lower), slide the shifter into neutral, and continue braking. Once in a complete stop, turn off engine. To start, repeat the process from the top.

Stop signs are tricky and they can be two handfuls, literally. Watch traffic closely, be a defensive driver while doing this, and absolutely anticipate every and any possible scenario. Adjust vehicle speed to minimize stops at traffic lights. Left-hand turns can be nerve racking, but it's doable. Use hazard lights and turn signals (hazard is always on whenever a turn signal isn't needed).
