I’m bummed to hear about a bad experience with the Librem phone- I was hoping that would be a better experience than I had with the PinePhone which was slow and essentially broken for calling and camera usage. It may have improved since last year but at the time calls would rarely work properly, either by not connecting, failing to interrupt the session properly, or have latent echo of one or both sides of the call. They provide several distros which is nice so your results may vary.
