Backup or not

So a few days ago my screen broke and it started putting in random numbers until my iPhone was unlocked. It did this by itself for 2 days until I took it to a shop for repair. When I got it back and it was repaired the phone was completely disabled and it said that it could be unlocked with iTunes. This happened because the phone wouldn't let me turn it off as the screen was broken. Anyway, I synced my phone with iTunes before, but for some reason there wasn't a backup anymore on iTunes. Now the only remaining options for me are either deleting from my phone or restore from iCloud backup. The last one sounds like a good idea, but my last backup is from may 10th 2019... I'm afraid to lose all my pictures and videos after may 10th 2019 so i'm not sure if this is the best option. But with the other option I don't know if I will even keep any pictures or videos...

Does anybody know the answer to this?
