Not sure if this is the place to ask, I recently moved to OKC for an internship and was looking into the local 2600 meetings, since I finally live in a city that has them. I found where they meet in the latest issue, but that's about all I know. I don't know any times or days or anything. I've tried looking around on the web, but also haven't found much. Does anyone know how I could go about finding any of that info out?
Out of the options you mentioned, Pixel with a custom rom (GrapheneOS, CalyxOS, etc.) is probably the best bet. Seconded by any Samsung that could run a custom rom, though I agree with others here that the hardware is better on the Pixels. Plus they have extra security hardware features that will be better. Of course, if things are weird with your telecom, that might effect things (trust me, been there with an Ubuntu Touch phone before.)
Another option you could look at depending on where you are is Murena's phones. They have a bunch of options pre-flashed with their de-Googled rom /e/ os. Not my favorite rom, but still not bad! And of course those can be flashed with another rom if you want as well!
