They still exist? I was under the impression that they are abandoned.

Do I use BTRFS or ZFS? I tend to use ZFS because of its advantages when making backups. What would you do?

Usually VMs are usually I/O starved therefore I would try to go as lightweight as possible and chose Ext4 or XFS (depending on what the VM is used for). The VMs can be backed up whole by Proxmox. You have more than enough space to do that and it's considerably easier to set up. And honestly how big could the containers and VMs be? I guess the containers are 50-200 MB and a VM a few GBs. That's almost nothing.

Do I use QEMU/KVM virtual machines or LXC/LXD cointainers? Performance wise QEMU emulating the host architecture should be the way to go, right?

LXC containers are way more lightweight than VMs. I depends on what you want to do. Docker and a file server work better in a VM so far but Pi-hole and Jellyfin run perfectly in a container.

I shy away from running all services as Docker on the same machine for backup/restore purposes and rather have VMs per service. Is there anything wrong with this approach?

I would go for LXC first. If that isn't possible or too cumbersome I would try docker (in a VM) next and one-VM-per-service last as they need the most resources.

I’d love to keep NextcloudPi (because it’d make it easy to migrate settings and files) and there’s an LXD container for it. Would you recommend doing a switch to Nextcloud AIO instead?

Sorry, no idea.

I’ve equipped the Deskmeet X300 with a WiFi card and antennas. AFAIU trying to use WLAN instead of LAN will create some trouble. Has anyone running Proxmox on a machine with WLAN insteal of LAN access successfully?

I would always try to connect it to LAN.

I’m aware that Proxmox comes with a firewall, but I don’t feel very confortable using a software firewall running on the same machine that hosts the virtual machines. Is this just me being paranoid or would you recommend putting a hardware firewall between the internet access and the Proxmox server?

No idea. I wouldn't mind a firewall container. If something breaks through you are fucked one way or the other. The firewall in your router isn't much different than any other.
You should always go for Wireguard or another VPN to access your network from the outside.

What else should I think of, but haven’t talked about/asked yet?

Just give them a look.

And it seems you are ignoring Proxmox' LXC. They are one of main reasons to pick that software.

Edit: As an additional note: I ran about 6 or 7 VMs on a mini PC (Intel N100) with 16 GB RAM. RAM was almost used up and the cpu was at ~15 %.
I then switched mostly to LXC and only one VM. The cpu was now at ~1% and RAM usage went down to 3 GB while still providing the same services as before.
The power of containers, baby! :D

If the latter is Safari, then WebKit-based browsers are available for Windows and Unix-likes too.

Which are? Please list a few current ones that have reasonable backing and at least a mid-size community.

That only gives you a biased and incomplete insight.

WHY DO YOU NEED MY DATA TO MAKE FIREFOX WORK???

They don't care about your actual data, they care about how Firefox is used. That's an incredible important piece of information every developer needs to know.
How else do you get to know, what's working right and what doesn't? How do you plan development for the next years if you don't know what to develop?

This is about throwing millions of $ at the right thing. If you miss you are fucked.

Amarok is the other wolf. I know it looks deceptively similar.

Pics or it didn't happen.

'nough said!

No Greece? Also no India, Indonesia and Japan? Damn that's unexpected.

They'll shut it down if you send more than a few megabytes down that tunnel. It's ok if you just need a connection (for ssh and stuff) but anything that generates a lot of traffic will be blocked.

I think I didn't describe well what I wanted to say. English isn't my native tongue.

The solution I propose is to increase population density. If you increase the population density the infrastructure costs per capita will go down fast. You can see the results in the USA, almost all cities have a lot of debt just because the residential areas are so large and thinly populated.

but what that sounds like you are saying is that people should be living in apartments right by their offices instead of having their own houses

No, please no! I don't think anyone would want that. A healthy 2-3 miles distance between home and work should be enough. Some people might like to live close to their workplace but I'm not one of them. Some might want to live in an apartment or condo, some might to live in a house (especially those with large families).

I still stand by what I said

That's perfectly fine. I don't mind. Everyone has the right to their own opinion. I have 10 of them. Nine tell me I'm not crazy and the tenth one is humming the melody of tetris.🤪
