If you want something like graphene or calyx (I.e. with additional de-googling and security improvements), take a look at DivestOS: https://divestos.org/pages/devices#device-blueline
Crdroid (which claims performance improvements, but also has a lot of customization options; reminds me of now deceased resurrection remix) is also good but doesn't seem to officially support your device. There may be some ports on XDA, tho.
All clothes are no-iron clothes if you DGAF enough :)
