Are there plans to keep the blockchain/node size small enough to maintain decentralisation?
I assume with "blockchain/node size" you mean the growing size of the immutable ledger database. The current growth rate is pretty linear. In the last 100 days it grew from 7 up to 10.5 GB

How long does it take to sync a node or a Daedalus wallet? What factors does it depend on?
It all depends on your hardware, mostly CPU and network connection (yours and your peers), but on most newer hardware you should be able to sync it within a day right now.

Killed probably means it was killed by the OOM (Out Of Memory) killer. If it was OOM killed, there will be a message in the dmesg output.
Running the node requires at least 8GB and you should have 4G ...

Storage requirements for mainnet/testnet cardano nodes?
Yes, the testnet takes less storage. This is what I got when I installed them a month ago:
Testnet: 11 GB
Mainnet: 46 GB
I haven't updated it again, but it's roughly around those number

You just mean to have all the disk storage the node needs on an external drive? Sure that is possible. How you do it depends on which OS you are running on (eg Windows, Linux, Mac).

If your connection(s) to the IOHK-hosted relays was in fact the problem, then yes, connecting to other SPO relay nodes should help alleviate the issue.

Why is my cardano-node not doing anything?
Check your configuration file. This looks like your logs are going to a separate file. I've seen this with tools like cntools where they redirect all logging out of stdout into separate log files.
