Not OP, but one thing I do is having a fake name on my mailbox and doorbell. I figured my neighbours don't need to know, and parcel services don't care. I don't legally live on that address, so that helps.
I also try to keep my browser's headers more generic, especially the Accept-Language header (not applicable or particulary helpful for US residents, though). The rest (VPN, [and therefore] no Google and no social networks) I wouldn't consider an obfuscation.
To my fake name (from family and friends), anything official goes to the mailbox at my real address to which I have access to. But that rarely happens thanks to e-government. Because of presumed delivery, there's no benefit in receiving that kind of mail on paper, so I opted-in.
For e-mail, I use a domain with a catch-all mailbox. I rot13 the service name or whatever in the local-part to identify where the e-mail got leaked/sold from, which I feel like happens more often than not when buying anything from small e-shops.
I enjoy obfuscating things s much as possible just to be a tiny grain of sand of irritation in big data’s crotch.
I’m also maybe a bit oppositionally defiant but I enjoy hiding my shit. Why does anyone assume a right to know everyone’s business?
