Yup, they can give you a secure boot chain that's otherwise hard to prove, and I've worked at places where (for example) disk encryption keys were protected by TPM encryption, using TrouSrS.
They can also often be used as a (slow) source of hardware randomness.
Most modern intel (seris 8 onwards) and AMD Zen onwards have fTPM too. Often these can be enabled in the bios during upgrade then disabled again.
Personally I upgraded to Win11 the moment it became available, but that's because I want to continue my run of free MS windows forever and I only ever boot into it to play games, with even that becoming less common.
