What would you suggest as a good alternative? Lineage?
Nothing is really a direct alternative to GrapheneOS overall, it leans into security a lot more than other privacy ROMS. However, if you just want to deGoogle your Pixel and improve its privacy, another option is iodéOS which is a fork of LineageOS with some further privacy enhancements and an inbuilt tracker blocker. Updates are a couple of weeks slower than GrapheneOS, but you can lock the bootloader following installation. You can check if the Pixel you want is supported here. There are also community builds for some of the unsupported Pixels. The 9 series hasn’t been added yet beyond a community build, although I’m sure it is coming soon.
