As I come to grips with the limitations of SNARKs for mechanisms that have a mix of private and public data, I have a question: what do you think about FHE? Do you think the advances of the last 2 years will lead to a Moore’s law in practical code, like we saw post Groth16 or not?

FHE still has practical limits that preclude it from being a "magic black box", namely you have to gatekeep the final decryption step somehow, and it ends up in practice often having similar constraints to MPC. So I definitely look forward to it (as well as side quests like much better PIR) but it's not a panacea

Yes although I’d argue the communication complexity (in rounds) ends up being lower although you have to have more bandwidth (e.g. decryption ideals) per round; but point well taken
