That's the wiki I used too. I found it way better than the other (fextralife?) one.

General advice to OP: If you're anxious, I would advise that you do a full, proper save (i.e. not a quick save) periodically.

When I get home, I'll have a wee look to see if there are any significant missable items not covered by the above guide.

But there are some collectibles and the like that are mutually exclusive, albeit not many.
