Disney said Resistance will head to Disney Plus after the second season is over. The CW Micro Series is joint owned by LFL and Cartoon Network/WB I believe so that one would be trickier to get on Disney+.
Solo and TLJ will be heading to Disney+ once their Netflix deal is up (2020). TROS will head to Disney Plus after the home release (late Summer /early Fall 2020).
I read somewhere that TBS/Turner worked out a deal to extend ownership of TV rights in exchange for letting Disney stream the OT/PT. So OT/PT will not be on Disney Channel/XD but they will be on Disney+.
As for the other old stuff (Droids animated, Ewoks animated, Ewoks movies), Disney has been quiet about those (and the Holiday Special and the unaltered OT cuts as well).
