Hey Tara, this has been my pet peeve the last few months! I’ve tried a few, hoot suite IMO is clunky and doesn’t support things like multiple Images. Sendible has been the most impressive so far but still has limitations due to the APIs for each platform. The only one to offer all post types (but only for IG) is the creator studio but as you mentioned it is not a planner and has not organizational tools. Sendible so far is my front runner (for now )
