September will be perfect for riding, warm to hot in the valley but coast and mtns will be fine.
I would head out of SF over Mt Hamilton then cross valley to Sequoia NP.
Then north thru Yosemite and over Tioga Pass.
Go north on Hwy 395 (checkout Bodie Ghost Town) and over Monitor Pass to Hwy 89 then on to Lake Tahoe.
Keep on Hwy 89 and go thru Lassen Volcaniic NP.
Back down thru valley near Mt Shasta and over to the coast at Ferndale.
Here you can take the Lost Coast Hwy south thru Humboldt National Park and pick up the Avenue of the Giants Hwy.
Stay on Hwy 1 south thru Ft Bragg (stop at North Coast Brewrey) and returning to SF thru Muir Woods National Monument and over Mt Tamalpais State Park, crossing the Golden Gate returning to SF.
Save Napa Valley, foothill Gold Country Hwy 49, Death Valley/Vegas and southern Calif for motorhome part of trip where you will enjoy the air conditioning.
To answer a couple of your questions:
Drivers not as motorcycle friendly as Europe and laws not as flexible/forgiving.
1. It is legal to lanesplit (aka laneshare) in Calif only (no other states allow it).
2. Filtering to the front at signal lights is not appreciated by most car drivers but some riders do it anyway (I do not).
Both of these can get you a ticket if the Officer thinks you are being UNSAFE.
3. No parking on sidewalks.
4. Hotels are plentiful and easy to find.
5. Keep right.
6. No travleing or passing in the breakdown lane (shoulder) of any roadways.
7. Lots of Double Yellow no passing zones and they mean it, especially in Parks.
8. You can turn across one set of double yellow to exit roadway. Double double yellow is treated as a curb and do not cross.
