Local Viking/Local Brand Manager I have been using for about a year, and while they have their share of bugs that pop up, they are pretty solid about correcting things and implementing suggestions in my experience.
They maintain a public-facing roadmap:

You can schedule posts, and in particular, my favourite is to be able to schedule recurring posts using spintax in the content and the ability to apply an EXIF template to the photo included in the post with the dynamic date included to avoid duplicate posts.
You can create a gallery of 35 photos for example and then schedule it from March 1st through March 31st and it will schedule a post every day with 4 days having 2 photos. You can also schedule that gallery to more than 1 location concurrently (handy for a multi-location brand).
I have 4 Google accounts attached to my account but they offer unlimited accounts in all their tiers (I can't imagine a scenario where you would need more than 1 account per location).
You can't currently include video in the posts from the platform, but you can include photos and select your CTA option.
They also have decent reports you can schedule, keyword tracking and geogrids included.
