I recently spent some time looking into exactly this. I ultimately decided to go with an N100 running Proxmox. It is a wonderful compromise between power utilization and compute.

The N100 was roughly $50 more than the Pi 5 (after adding storage to the Pi). The idle cost to power both is roughly $5/year for the Pi5 and $10/year for an N100 (based on local electricity rates YMMV).

I'd argue the Pi still has a purpose: Running it off of battery/solar is likely better, it is physically smaller, and it also has pin-outs and documentation/software to support it. If all you're after though is a small-low power usage computer, it may not be the first choice anymore.
