Fedora is really great, but it is a bit bleeding edge in that there are lots of updates all the time. I have found Arch with an LTS kernel (I use older hardware) to be about similar in terms of stability.
Example 1, Fedora ships with zram swap by default instead of allocating a separate swap partition. Basically it's compressed ram, good enough because when you start to swap your system is already on its knees, but orders of magnitude faster than reading from disk, and you don't need to allocate a separate partition.
Example 2, On Fedora when you format with / with btrfs, it'll enable a really fast zstd (level 1) compression on your volumes. It might save you a few gigabytes, it consumes a imperceptible amount of CPU time, and reduces the write amplification effects on SSDs and NVMe.
Fedora gives you these out of the box, while on Arch you have to be aware of them, and I bet you don't have any of these free wins enabled on your system.
I love Arch Linux, but Fedora is IMO a better desktop experience.
I still have a 6 month upgrade cycle on my server, but I don't need to deal with package updates changing things.
