Thanks for the reply and for the work you put into Mobile Linux! I enjoy (a moderate amount of) tinkering and use Linux on both my work and home PCs, but my requirements for a phone are a bit more demanding - a phone has to be a device which I can depend on to work e.g. when I get a call, if I forget to charge it overnight, when I need to quickly scan a QR code to access some website on the go etc. So I'm afraid I'm not in the market for a Linux phone right now, but I hope (thanks to people like you) it will get to that level one day...
You might consider getting a refurbished Google Pixel and put in your choice of GrapheneOS or Calyx. For someone like you it may be a good compromise, and maybe at some point you get a side Linux phone to eventually transition towards.
