Sir, you answer your question yourself. Those people are not our role models. After the Rashidun, it wasn't even a Caliphate, it was monarchies and tribal fiefdoms and other things that prioritize ethnicity and race to hold on to power and are closer to the non-believers than to Islam. They were no less unguided than us today.
The Prophet married a freed slave, women richer than him, poorer than him, different tribe than him, even different religion than him (two Jewish woman and a Coptic christian woman)
