GSW Homomorphic Encryption
The actual schemes are using $\mathbb Z_q$, but the implementations of those schemes in practice need to be mapped into 0/1 bits.
In the implementation, you need to map the field into 0 and 1. In most ...

Decryption of Naccache–Stern cryptosystem is not guaranteed for large keys
The question's $g$ is not suitable. Try e.g. $g=30359963453720570073793540267704$.
I read the question's condition 6 as: $\forall p_i\in\mathcal S,\quad g^{\varphi(n)/i}\bmod n\ne1$, with $\mathcal S$ ...

fully homomorphic encryption without bootstrapping
Looking at this survey published around the time of your question (Nov. 2022), the "unleveled" (unbounded) schemes described seem to all utilize bootstrapping.
This (pre-print) is a paper ...
