fundamental problems with assemblies
Can you share an assembly ?
I have no problems creating properly functioning assemblies and based on my experience the problem isn’t the software 😉

I could be wrong, but I don't think you are going to find the equivalent functionality in Fusion.
Attach your dummy set of files for experimentation in Fusion.
correct. Fusion does not yet support Replace Component. But all other of your "fundamental problems" should be addressable using common Fusion assembly practices such as Joints, Ground, and Rigid Group.

If you switch to using “linked components” in your assemblies, you can solved a lot of your replace problems with the Save As and Replace command. Take a look at this blog post to see it is action from the included video.

Sorry Jeff, I meant to direct my post to @Anonymous

Yes, but you also lose a lot of the speed inherent in top-down design workflows, which is Fusion 360's strength.
It also does not really address the problem it rather evades it!
can you post a video of what you are seeing, and describe what you think is incorrect? I am unable to move the grounded components in this design. How are you attempting to move things? Dragging a component? Or using the Move command? If you are using Move, are you sure that the move type is set to Components?

... here I can move each component, also grounded
I don't see that at all in the assembly I downloaded.
Accepted solution
I don't think you sent us the correct design. This is the top level of the design from the link you sent:
This looks much different that what is in your video:
I think you sent us only the sub-assembly.
However, I think the key is in your explanation: " part from grounded subassy". You have applied the ground to the subassembly, but that does not ground the child components under that subassembly:
You need to apply the ground directly to the lowest-level components (or perhaps create a rigid group, and ground just one of them)

Please use the Autodesk screencast tool. We have some minimum standards here on the forum! This isn't Facebook!
I have a hard time looking at a video taken with a handheld phone in portrait mode.
As opposed to any other CAD systems I am familiar with in Fusion 360 all components by default float.
So you'll have to ground them. However, grounding is only local to that assembly.
You can also use a rigid group joint between the component and the top-level origin. That is maintained when you inert the design into another assembly.
What grounding does it that it locks the origin of the component to the top level in that design.
However, when you insert that design into another design, that grounding becomes irrelevant.
You can also only ground an assembly if you make sure that the components in that assembly are joined to the origin of that assembly.
90% of "strange" behavior in assemblies is down to not managing component origins properly.
