Irving is a mellow recently repaved hill starting around 34th avenue. It's beginner friendly.
Lawton headed west towards the beach is medium speed hill. The top is at 33rd avenue. Not sure how fast you skate, but once the light hits red at Sunset count to 10 and you should make it. Or just watch it for a few cycles and judge how much time you need to give yourself.
Quintara is the fastest in the Outer Sunset and is mostly 4 way stops at the intersections where you will be going the fastest. Don't blast 2 ways without a look out. That's skateboarding's version of Russian roulette. 15th and Quintara is 1 block of steepness. You can hike up higher if you feel like it.
The longest hills in the Sunset all head west towards the ocean.
Balboa in the Outer Richmond is really fun.
If are going to Miley, this is a fun / fast hill with manual pads every block for the first half. Just gotta be careful at the 2nd half passing the cliff house. Cars regularly back out of the parking spots and won't see you coming.
