i’ve been meaning to switch fully to signal, but since not many people where i live wanna switch too, i often tell them to just call me. Is that private enough as a privacy conscious individual?

No they are not. Famously last year it became public knowledge that the built in lawful intercept hardware backdoors across the entire cell phone network and pstn were compromised by “the Chinese”.
FaceTime audio, signal calls and perhaps WhatsApp use encryption in transit, so those backdoors don’t affect them. I don’t know about other data calling methods.
