Running a node is pretty useless unless you're running a proper lightning routing node
It isn't. You can run node and use it for Bitcoin onchain payments too.
For Lightning I recommend having setup with two SSDs in a mirror.
You're right, what I meant is running a dedicated machine as a node isn't needed unless you need always on lightning routing.

There are other use cases where you might want always on Bitcoin node at home. For example, running Electrum server there and connecting wallet(s) on your mobile phone to it.
