I was daily driving arch for 5 years and decided to switch two months ago just like you now and running Debian 12 happily, tried fedora, set subvolumes to timeshift btrfs to work because it was not installed out of the box, and after update from 38 to 39 with official gui update tool, it broke and locked away ssd so i had to recover data, after that i installed Debian 12 and had no problems at all, machine ALWAYS ready to work and stable as fuck, heavenly experience so far actually
