Clutches will last 80,000 miles on most cars unless driven unsympathetically by either dumping the clutch or riding it frequently. Fluid and spark plugs are some of the cheapest maintenance you can do on ICE cars. Timing belts, aux belts, water pumps, bearings are much more expensive wear items and I'd be much more concerned about those personally.

You should however be changing your brake fluid every 2 years regardless of whether or not you have regenerative braking. Brake fluid degrades over time as water gets absorbed.
