With Synology your not getting the latest greatest hardware your basically buying the DSM operating system.
DSM is a really nice one stop shop though.
Unless you know you’re doing something DSM can’t support it’s hard to go wrong with Synology.
Just make sure whatever version you buy has access to the DSM apps. For instance, you said you use docker, so make sure the Synology device you’re interested in works with Container Management.
It shows you’ve never been to a third world country. You have no idea how bad things can get and people still chug along.
