I'd say the most important things are, in this order:
Drive slower
Accelerate lightly
Reduce unneeded consumption
Vehicle maintenance
I hope there's something of an ocean breeze keeping you cool. Warm temps will improve FE if you can stand to drive without the A/C. A full manual transmission helps a lot since we run with the engine fully off quite a bit. Definitely drive slow. Over a long distance I've found my car can sustain 55 MPG at 32-35 mph with a little pulse and glide and engine off coasting used at the right times. My personal goal to work and home is 50 MPG everyday.
Don't drive aggressively, Take 20-30 seconds to reach your speed. The CVT will automatically keep you at the optimum revs. Unfortunately you still have a torque converter. Get used to the timing of the lights in your area.
You will do better to gently accelerate to 5 or 10 mph above your target speed and easily make the light when it's green than to wait until its yellow (or orange) and floor it. The earlier you can recognize that you will not make the next light the sooner you can get off the gas. There are a few lights on my commute that always turn red before I get to them if I don't make the light a mile or so before hand when it's green. For these I basically roll to a stop. Get off the gas sooner on exit ramps. If you can, don't use the A/C. Unless the windows are all the way down at 55 mph+ you will use less gas with the A/C off.
I pump my tires up to the maximum pressure listed on the sidewall. This will cause a harsher ride but will improve FE noticeably.
I started doing these things and noticed the benefits immediately, the only thing for me to do differently was to do even more: Drive even slower until I found an ideal speed for both fuel consumption and the timing of traffic lights. Accelerate even lighter and skip unnecessary gears. Improve my understanding of the timing of the lights in my area.
