Might be interesting to do an overview of platform and processor security technologies (trusted boot stuff, memory encryption, ...) and comparison on platforms. (Right now I'm personally trying to figure out exactly what the amd v2000 zen2 embedded will support, vs. epyc embedded 3000 or epyc embedded 7000). The intel stuff has a long history (from MS/Intel Palladium -> TPM/trusted boot -> TXT -> SGX - TDX), and there's also ARM TrustZone (not sure how the bigger server ARM platforms handle this, and now there's the Mac M1 stuff).
Slightly relatedly, a series on bios, uefi, other platform boot (power, arm, modern mac), and third-party software (coreboot, particularly).
