I attended Autodesk University 2019 this past November. I took an hour long class on large assemblies and will give you the answer they gave me. Large assemblies can be look at 2 different ways. Direct modeling (NO TIMELINE) with thousands of components and bodies or a parametric model with tens of components all with timelines longer than your screen is wide. I am in automotive so large assemblies mean something different to me. 1 seat with every nut, bolt, wire, and frame , etc locks up Fusion if In not careful So "No" to the large assemblies unless you only use Direct Modeling(DM) - This is not Catia which owns Fusion in this regard. Example: I brought in some automotive data-700 Mb step file. Catia was using about 2.8 Gb ram. Fusion was using 12 Gb of ram (after 45 minutes of work it was using 18 Gb of ram and crashed) There are a few tricks that can help Fusions performance but these are only workarounds. If you are a designer and you use sculpt mode with parametric modeling, then you need to use all of the tricks available: -Use linked data (this helps a lot) -Turn off active component in preferences. Transparency in Fusion eats up a lot of processing power. -LOD (Level of detail) should be set to low -Do not turn on anti-aliasing or ambient shadows -use shaders/ materials without reflective surfaces -if you have designed a part that will not be changing, consider right mouse clicking on it in the timeline. Turn it into a DM feature. this erases all of the history linked only to THAT part and not the entire file. (BTW, you can only find this feature by right mouse clicking in the timeline at the moment) I share your frustration with this aspect of Fusion. I am about to start looking into Inventor myself or other software like Creo or SolidWorks. Keep in mind that I use heavy data sets and refuse to use Catia(too complicated and too expensive Kevin

I would recommend going to Create, then Derive, and creating a new design, selecting only the body (or bodies) you wish to export. Once you have saved the new design, you can easily go to File, Export, and choose the file type you need. Hope this helps!
