Centralization tradeBuilders/relays that protect you can also censor you. You need a fail-open path with worse UX but safe defaults.

function chooseTransport(bool preferPrivate) internal view returns (Transport) {
    if (preferPrivate && flashbotsHealthy()) return Transport.Private;
    return Transport.PublicGuarded; // tighten slippage/deadline if we fall back
}

Design for both happy-path privacy and safe public fallback; inform users which path is active.
