I’m running Arch on my RPI 4b+ and quite happy with it.

The installation was pretty simple IIRC - I did run into some issue with uboot which was easily solved by searching for the error on the internet.

Arch Linux ARM ships with a mainline aarch64 kernel and uboot by default, but if you are interested in running the RPI kernel and their boot loader, there’s a custom pacman repo and instruction on the forums: https://archlinuxarm.org/forum/viewtopic.php?t=16144

All in all I don’t think arch needs that much maintenance on a non-critical home server - just make sure to check for config updates every now and then and reboot after kernel upgrades.
