Look into installing a custom ROM, some phones are not supported but many are by at least one custom ROM. I personally installed GrapheneOS and recommend that or calyxOS (never used it but hear good things) but those are only available for pixels, iirc LineageOS has the widest support but also isn’t quite as secure. F-droid and Aurora store for apps.
How did you go about de-googling your phone? I’ve de-googled my services but I’m just getting started on the phone.
