What distro would you recommend for a 32-bit old Acer One laptop?

It's an old model (Acer One D257) Processor is Intel Atom. Memory is 1GB DDR3 with 320 GB of HDD. I currently Have MX 21 running on it, but I need to reinstall because I forgot the root password. Since I'm reinstalling the OS, I thought I'd ask here for recommendations for an OS that makes the most of this oldie.
