Where to open a 529 (CA) and what custodian? Fidelity, Vanguard, SFC, CollegeShare, etc.

As a CA resident, I understand there are no tax benefits for us opening a california plan. I've heard great things for Utah, Maryland and Alaska for other state 529 plans through SavingForCollege website. However, trying to sign up i see SFC requires some membership subscription which is ridiculous to me. On top of that, the fee for Alaska seems to be .15% - .88% and Maryland is like .13% - .67%.

What 529 options might you recommend?

I am okay with a target date index but would also like some control and strong investment options. Low fees are crucial and no subscription costs...I understand this gets asked a million times, but research didn't show where (website) people are opening accounts up and these options often obfuscate their fees until after you sign up. Thanks
