imo just get a pixel. unlockable bootloader and almost guaranteed support from pretty much every major privacy-related android fork. and many of them are building support for the titan chip if they dont have it already
I also have a Samsung phone besides a Pixel with GrapheneOS and I just ripped out Gemini, most of Bixby, etc. using UAD-ng. It's very clean now, but I still have all the customizability of OneUI, Good Lock, etc.
Unless you really have a large ethical problem with paying for any google product, I'd just recommend to get one of the previous-gen pixel devices. They are a lot cheaper than the Motorola smartphone coming out.
