CipherStash founder here: FHE isn't the only option here. Specialized searchable encryption schemes exist and are much faster than FHE. Different flavours can be combined to create a comprehensive search system which is very close to the performance of plaintext information retrieval. FHE remains an option for generalized computation but can be reserved for small datasets that have been narrowed down using fast searchable encryption.
I don't think FHE is the solution to PIR but it might well form a part of it when combined with more practical approaches.
Protect.js makes encrypting sensitive fields in Node apps like Next.js simple for devs without the need for expertise in cryptography.
It supports searchable encryption, integrates with Auth0, Okta and Clerk and works with the performance-focused ZeroKMS key management service.
