I'd probably not go with a T-Version, as those are capped to a specific TDP. So if you need more compute power, it'll limit you fast earlier than a non-T CPU. Idle draw is basically the same, and usually the state of my hosts is idle or full throttle.
Also T-Variants tend to be more expensive.
Storage is a thing to consider as well. At best those machines offer a single NVMe and SATA, a lot even only one or the other.
Servethehome does have a nice series about those mini PCs, so best to take a look there which one to pick for your needs.
