I use Void 64 bit as a daily driver . It runs my VM’s with virt manager and I fiddle with docker containers there . It has been there for 5 years and I only ever had one rolling release update that caused issues. It is the glibc version ( not musl).
I have and old pentium laptop that has Void 32 bit. It runs OK there with Xfce as the DE.
Void can handle .deb files. It has a converter that translates them to .xbps. I rarely need it because the Void repo is nearly as comprehensive as Debian.
Dont be afraid of rolling release. Developers have learnt how to manage it now. Those horror stories from the early days of Arch are history. Rolling release is the way of the future.
The other distro that has 32 bit is antiX. Antix is designed for older smaller computers. You should consider antix as well as Void and Peppermint.
