Use a modern filesystem like btrfs or even lvm with thin provisioning to solve that problem. Separate partitions for ease of backup, but they all pull from the same pool of storage.
On my PC and all my home servers I keep my root partition at 10GB and haven’t had any issues (although I keep everything that isn’t hardware related or a system utility in home).
On my PC I crammed arch, all of KDE (+extra KDE utilities), and some other system stuff like LACT and distrobox in the 10GB root partition and run almost everything else as a flatpak installed to home.
On my servers I do the same thing but all my services are in podman containers in /opt.
Having all the software needed to make the machine work be isolated from my custom home junk makes me feel better, and I like that I can mount root as read-only to make it immutable
Separate /home is such a scam. Never have I run out of home space, but boy is 27GB not enough for a root partition that runs any kind of service.

I think that there’s a reasonable argument for a separate home partition on a multiuser system. Means that users can’t fill up root.
But a lot of systems aren’t multiuser these days.
I have / on SSD (less writes) and /var and /home on HDD
It’s the opposite for me.
