Man, at this point you should think about your treat model. Are you a high profile target?
If so, choose security over convenience, but if you only want your privacy, you probably can have a comfortable balance between security and convenience.
You can set KeePassDX to use a pin for quick unlock. It does not have the remote access feature, but i use Synology Drive to keep the file synchronized, and it does a decent job of autopopularing fields.
