Wudhu from Quran vs. Sunnah way-am I messing up?

Assalamu alaykum everyone! I’m still pretty new to Islam, just over a year now, and alhamdulillah my husband has been a big help. He grew up Muslim and showed me the Sunnah wudhu: washing mouth, nose, face, and arms three times, wiping the head, washing the feet three times, plus the ears. Honestly, it was really tough for me, and astaghfirullah, sometimes it even made me put off praying. Then while reading the Quran, I saw that it mentions washing the face, arms, wiping the head, and washing the feet-no more. That felt a lot easier, so I started doing it that way. It turns out my husband’s method is the Sunnah way. Now I’m stuck: is the Sunnah wudhu obligatory, or is it just recommended with more reward? I’m not trying to ignore the Sunnah, inshaAllah one day I’ll get there, but right now I struggle enough with wudhu and prayer, and sticking to the Quranic steps really helps me stay consistent. Jazakum Allahu khayran for any advice!
