I've been eyeing the Fairphone 6, which has a de-Googled OS option and looks interesting. It's supposed to be more environmentally and ethically responsible, somewhat modular, and with 2-day battery life. The user reviews on their site complain of some software bugs but also say they're releasing updates to address them.
