A couple questions on Syncing

OK, so a little clarification upfront before i get to my actual questions.

I use LRC and LR across a few devices. My desire is to have full copies both on the cloud (using LR) and a local library (using LRC).

• My Import process looks like the following:
  • Import from SD Card to LR (cloud)
  • Originals are downloaded from Adobe CC to the local machine via LRC
  • After the originals are downloaded by LRC to the designated local folder, I move them into another folder using the following naming structure
    • YYYY-MM-DD - Description
  • After moving the photos into the descriptive local folder, I create a collection by right-clicking the folder and selecting "create collection". 
    • I select "Sync with Lightroom" to create the same collection (album) on LR

The steps above result in an original copy on Adobe CC as well as an original copy on my local machine. This also maintains the linkage between both LR and LRC syncing all changes wherever they are made.

My questions:

1.  When I create a collection in LRC and sync that with LR, is LR making the connection to the full-size image in Adobe CC? My concern was that I was overwriting my original in Adobe CC when I shared the collection from LRC (since you can't share full-size photos from LRC to LR).
   
   
2. Is there a better way to accomplish this? My current process is slow but it has the end result I am after and things between LRC and LR are mirrored in a way that makes my "OCD" happy.
   
   
3. My understanding is that when using LR you are using a preview (smaller file size) anyway. Should I just bypass the Adobe CC backup and save myself a lot of time? I have other back processes anyway so not worried about losing data. 
   
   
4. Assuming that with no original file in Adobe CC (preview only), you lose the ability to export the full-size image. Seems like common sense but given how wonky this ecosystem is it was worth asking.
