Well, 32-bit support is becoming rarer and rarer these days, and ARM is a whole different beast altogether, but but there are still some 32-bit ARM distributions around.
The link below should provide you with some guidance, even though not all of the listed distributions support 32-bit — for one, Manjaro is listed there too, and as 64-bit-only.
Thank you for pointing out that site to me! I’ll be looking into it some more…
I put the memory card into an ARMv8 Raspberry now, but somehow, it still doesn’t boot. Even while the card was written with Cinnamon’s Bootable USB Image Writer.

Take the list with a pinch of salt, aside from the general ‘ai written slop’ of their articles, there are several inaccuracies, regarding Arch Linux ARM in particular
Supports armv5, armv6, armv7, and armv8 (aarch64) — covering everything from Raspberry Pi Zero to 64-bit SBCs.
Runs on Raspberry Pi (all models), Odroid, RockPro64, Pine64, and other custom ARM boards.
No longer supports armv5 and armv6 for years now, so no support for original Raspberry Pi and Raspberry Pi Zero, their website don’t specify the RockPro64 in platform
