Will I still reach Jannat al-Firdaus after crossing As-Sirat?

Bismillah, I hope you're all doing well. I've been feeling really anxious about this lately. I want to reach Jannat al-Firdaus so badly. I'm trying my best to improve in many areas of my life to raise my chances, but the thought of the Qantarah bridge honestly terrifies me. From what I know, it's like a final settling of accounts that cleanses the believers' hearts before Jannah. My worry is, if my good deeds get taken to make up for someone I've wronged, can I still make it to Jannat al-Firdaus? Since our rank in Jannah depends on the weight and quality of our deeds, I'm scared that if my good deeds run out and I end up carrying their sins instead, my station will drop a lot. Of course, I'm aiming to fix all my mistakes in this dunya before Qiyamah, but I still need to know. And another thing: what if I've wronged a non-Muslim? They won't be on that bridge, so how do I compensate them if I don't do it in this life? Jazakum Allahu khairan.
