Have you looked at DataGrip from JetBrains or RoboMongo?

I have used both of those as DB tools. Currently I have no Mongo databases and only use DataGrip, but I understand it supports Mongo pretty well and it is a decent tool. DataGrip isn't free but does have a free trial. Also, I believe there are a couple of different plug-ins for Visual Studio code that work with Mongo, but I don't use it so can't say how well etc.
