It can help to download your local map for offline use. The default basemap doesn't have details like house numbers, but the downloaded maps should.

OsmAnd will do that. If you edit the destinations you can manually specify their order. Click sort there and choose door-to-door to get the most efficient routing.
The app takes some getting used to, but it works very well, and can act as a front-end for contributing to OpenStreetsMap.
See what's using the space. This will list any dirs using >100MiB:
sudo du -h -d 5 -t 100M /var
Interesting. In NC here. Not sure if there's a difference regionally. I was seeing that kind of RTT on ipv4, but ipv6 was slower. I'll need to give it another try. The last time I did was at my last place where I had the BGW210. I have the BGW320 now and haven't tried on that. Maybe that, or changes in their routing since then will make a difference.
Did I read right that it doesn't use systemd?
AT&T is the same. And the last time I looked they don't give you enough address space to host your own subnet. You get a /64 instead of a /56. And it's slower than ipv4.
Every few months I try it out, complain and then switch it off.
Obligatory: Debian.
But I'd be tempted to put Proxmox on it and then run containers for each function. Then you get purpose-crafted solutions for each use case, but can easily plug new functions in or shut them down based on what you decide later.
