Best option I can think of is privacy.com

You can create virtual cards linked to your bank account and the transaction data is masked when processed by you bank. All my bank transactions show up as NSA Gift Shop. My bank doesn't know where I'm spending my money. Yes you have to trust privacy.com...

Similar question: Android smart watches only connect to one phone. I like receiving silent notifications on my watch from my android phone. However I also have an Apple phone for work and would like a ring or some other small wearable (not a second watch) to receive notifications from my Apple phone.

I use Eufy doorbells, locks, and cameras. I realize they are a Chinese company, but that is almost unavoidable until the US gets back to actually manufacturing tech.

The reason I like Eufy is the local storage and no required subscription fees.

First quick check of the app with classysharkExodus shows the following trackers built in:

1. Google AdMob - "AdMob makes earning revenue easy with in-app ads, actionable insights, and powerful, easy-to-use tools that grow your app business"
2. Google Firebase Analytics - This logs user language preference and user location

I think Graphene OS was commenting about them on Twitter. I'll see if I can find the posts.

We need an online guide, based on make and model, on how to disable the transmission of this data.

Apparently not, I have a Pixel 8 Pro that I got free on a promotion from AT&T. The bootloader is locked on it and grayed out.

Not in the US. A phone "purchased" on contract is carrier locked and you can't unlock the bootloader, which needs to be done in order to install a different OS.

I believe NetGuard will act as a VPN. This will prevent you from using an actual VPN.

Since it is a free phone from a carrier it will be locked until the phone is "paid off" by keeping their service for a specified amount of time. Once that time has passed, then your best option is to have the carrier unlock it and install Graphene OS. Until then, there is not much you can do.
