So, I have started a secondary account recently, to optimize my chances with Lucky and high IV Pokemon from trading, Sinnoh stones from battles, etc.
At this stage, since the new account is still a low level, I have been focusing on it primarily, keeping it active on my primary device, and only using multiple devices (so I can use both accounts) during raid hours and events.
But, what I was looking into, was getting a Pokemon Go Plus, to again optimize this further. From what I've been told, using a Pokemon Go Plus is an alternative to the "Adventure Sync" option (which only tracks travel distance for candies and eggs), so these cannot be used in conjunction – it's only one or the other; which is fair.
So my question is – can I use the Pokemon Go Plus with one account, and the Adventure Sync with the other account, with only one device? Or do both accounts need to be logged in at the same time?

No
... because you can't be logged into two accounts on the same phone. You can store multiple Google accounts, but only one can be logged in; active at a time per device.
Adventure Sync credits distance to the account currently logged in and Go Plus is tied to the device, which in turn is tied to whichever account is currently logged in.
Your best bet is to get two phones, which lets you Adventure Sync for both accounts but you obviously can't connect a Go Plus to two phones at the same time because of how Bluetooth works.
