For regular wear, I like https://arcadebelts.com/products/hardware-alu-work-belt?variant=51798558671212 They have a bunch of other clasp styles that I havnt personally tired.
And for work; I like this one better than arcade, but it is larger vertically that normal belt. https://holstery.com/products/modbelt





I know this is not helpful to your immediate issues, but here are a few suggestion to prevent it from happening again
Don’t store important data in any default folder. Make your own folders, name them something so you know its yours and not a system folder. I like to start my folder names with “AA”, so they show up first in the list.
Backup off device. If SD maid didn’t delete everything, a drop in a pool could have. The general rule is to have 3 copys. 2 in your possession (phone, computer, home server, USB stick, etc) and 1 off site somewhere (cloud, at friend’s house, etc).
For the data you described, it sounds like you would benefit from storing it all in password manager like KeepassXC. It encrypts all of that, and makes cloud storage a safer option.
Good luck with recovery.
