linux phones aren't recommended currently for various reasons, they're just pretty unstable and have various security flaws among other issues.
i'd recommend looking into a google pixel and installing GrapheneOS. its open source, and pretty much as good as it gets for privacy and security on a phone. it really is an excellent project.
very easy to set up and install, plus amazing app compatibility, no bloat or garbage, etc. its overall a really good experience, i can't recommend it enough, had 0 issues with it.
either way, despite some of the other replies, i really would not recommend regular OEM android at all. android that comes with most devices out of the box is typically full of proprietary bloatware and spyware and other garbage that you can't remove, and isn't a great experience at all in general.
if you can't get a pixel for GrapheneOS, next best thing is DivestOS, followed by LineageOS.
