Fresh Windows Install
If I do a fresh install of Windows on a new PC and log into my Firefox Sync account, will it import all my data?

Based on other users' threads, I would say "often but not always".
Also, it won't be all data, just the categories covered by Sync (you can review what you sync on the Options page, Sync panel).
If you need a more complete transfer, you may need to do it the old fashioned way with copies of files and folders. Hopefully it's not too late to make a backup of your Firefox data?
You can copy certain files with Firefox closed to the current profile folder to transfer or recover personal data.
Note that best is to avoid copying a full profile folder.
