There are a few alternatives, more can be found but this is a selection of the most prominent offerings.
/e/OS: https://e.foundation/e-os/
GrapheneOS: https://grapheneos.org/
LineageOS: https://lineageos.org/
CalyxOS: https://calyxos.org/
PostmarketOS (based on Alpine Linux rather than Android, and what's used in Pinephones): https://postmarketos.org/ (for some reason the site is currently down)
