Personally I use Nextcloud, but as you want local only, I have used Thunderbird. It’s fine. Cross platform, open source, remote to local sync. Basically, it ticks all the boxes for a calendar/agenda.

Depending on what you are trying to do, not necessarily. NextCloud itself doesn’t really care, as far as I know, as long as it’s address doesn’t change. AIO on the other hand is setup in such a way that it needs a resolvable domain name and a valid certificate for https.
This could be done by spinning up your own certificate authority and dns server, but that is a lot of extra work and would be local network access only.
Another way would be to use a free domain and a free certificate from let’s encrypt. The downside here is that the domain authority could yank your domain at any time, for any reason (as happened to all of the free .ml domains recently). At which point your certificate would also stop working resulting in a situation where you may have to nuke and pave.
If you want to be local access only, I would pick an install path other than AIO. If you want to be able to access NextCloud remotely, purchase a domain name.
A VPN, such as TailScale would be considered local network in this situation.
There are a whole slew of ways to look at this depending on what “glasses” you like to wear, and also the type of work involved. I work in grocery logistics, moving groceries from where they are produced to the store where you buy them. Here’s a few from my “lens”:
My thought on this is if you want the flexibility of working from home, that’s fine. But don’t expect me to give a damn about what you think. The job is rough enough without an uninformed opinion trying to mess things up worse.
That looks interesting. Looks like they only ship within the EU though.
My biggest problem has always been the available range. The charging infrastructure in the South is largely nonexistent and I work 60 miles from my house. The only way I could go electric would be to gut and rewire my house to add a charger (The 120v one wouldn’t cut it) and have a way to top up the charge at work during the winter. The cost of the car itself is only half the problem for me.
I was looking real hard at the Lightning when it came out and was about to pull the trigger on the truck and everything associated with it when the towing range came out. Yikes! I haven’t been that disappointed in a long while.
I was thinking Darwin Awards but OK.
I currently use Jellyfin to stream my music collection. It’s all stored on my NAS and I can give access to whomever I like. Downside is that the iOS music client, FinAmp, is… not pretty. It’s functional, but not great. I understand the player situation to be a bit better on the Android side.
