Looking for an android compatible with a plethora of custom ROMs under 400 USD.

I'm from India and I'm on the lookout for an android smartphone that's compatible with a plethora of custom ROMs including but not limited to GrapheneOS, CalyxOS, LineageOS, and many more. I also want the phone to have these features:

1. Great durability - must survive hundreds of accidental drops and millions of tosses onto table, bed and other furniture. It must also survive water and other beverages being spilled onto it.
2. Great battery life and screen
3. Latest connectivity features
4. Dual SIM and SD card slot would be great but not required.

I'm willing to make performance and storage (64GB is minimum) sacrifices for these features.
