In most states, including California, you cannot count on getting Medigap later
You can buy any Medigap plan with no health questions in the 6 months that start when you are 65 or older and have Part B. After that, a Medigap company in California can ask about your health. It can say no, or it can charge you more. So if you join a Medicare Advantage plan now, you may not be able to get Medigap later. California has a birthday rule, but it only lets people who already have Medigap switch to another Medigap plan. It does not help you get Medigap after you leave Medicare Advantage.
One exception is the trial right. If you joined Medicare Advantage when you first got Medicare at 65, or you left a Medigap plan to try Medicare Advantage for the first time, you can switch back within 12 months. Then you can buy a Medigap plan with no health questions.

Original Medicare totals use the lowest Plan G price that California Department of Insurance, Medicare Supplement rate guide lists for a 65-year-old woman who does not use tobacco, $162 a month. A plan with no drug coverage counts drugs at full price, unless its members can add a separate drug plan. A plan name with a link opens a page where you can change the care level, the Medigap plan, your age, and your drugs.
