Alternatives to GrapheneOS

I'm looking for a new phone and I'm wondering if there are any comparable alternatives to buying a pixel and getting GrapheneOS on it. From my research it seems something like a OnePlus has much better specs, but I'm not sure if there are any good enough alternatives to Graphene that would run on it. If the context helps, I'm currently trying to remove as much reliance on large companies as I can in favor of self hosting off my home server.
