I've said it once, and I've said it again for well over a decade. The only google account recovery is creating a new account in 5 minutes. If doing that does not restore the full extent of the purpose for which you were using google's services, you're doing it wrong. Google accounts serve one purpose: if you are trying to use a google resource that requires an account. Example: save some marked places on google maps.…
what do you suggest for cloud storage? I've had better luck over the years with google drive to store my documents than a physical backup drive. But the thought of losing access to my account scares me
You have to decide how important your data is. You might divide it into a few categories and decide what you can or cannot afford to lose for each category. For example your password database and family holiday pics are often more important than nearly everything else! Then you decide how much money to throw at all this. It's all a big risk assessment thing.
If you will insist on cloud then please use two of them or one and a local backup system. For really important stuff you can buy a brand that you have heard of 128GB USB stick for about £13 (just checked on Amazon). That's bugger all cash! Buy 10 of them.
Please take responsibility for your data. Use cloudy stuff for convenience but do not lose sight of who really is responsible for it - you.
