I think any of those would work (including just using screws), but if you're worried about the shelf or standing leaning once the speakers are on them you could add some small gussets at the base as well as under the shelf. If it were me, I'd probably just mortise the whole post maybe 1/2" into the shelf and the base, and then use screws.
