In my opinion so far yes, I’ve only been on it a few weeks, but think of the immutable as locking down the root partition and any vital directories to the OS and not allowing your user to modify anything. In the event of a bad update, it’s easy enough to select the previous boot in Grub and be on your merry way.
I have a special needs adult step-daughter who’s PC I manage and I always need to keep it updated, setting it up on their Bluefin version which uses Gnome which she loves. So, I may do it this weekend. She’s currently on Endeavor OS (Arch based) but it keeps getting kernel updates daily it seems and with those a reboot. Additionally, for whatever reason, her system goes to sleep without warning sometimes so if I’m updating it, it’s gone to sleep. (Super weird). I’ve never had it do this before with Standard Arch linux so I think its something to do with Endeaver. I’ve never bothered to troubleshoot it to be honest. With a setup on the BlueFin (Aurora Linux is KDE), enabling Auto updates should be a breeze and then she’s golden for being updated without my intervention.
What about just buying Matter Bulbs? Or supported WiFi Bulbs? I have 4 which work nicely! Aidot brand so it’s not known brand but it was good priced. I know you said they were three way switches so that may matter if you are wanting to utilize the 3 way dimmer, but with HA, it should be easy to do!
This would also be depending on which lights you want to control, as some may not be controllable such as maybe the bathroom lights. As an apartment dweller who rents, I put mostly smart lights every where I could in my home so I can control which ones come on or off on a schedule. Change colors as well to help set the mood with my floor lamps etc…
