I know I've seen this topic before, but I have to ask it again. Is
caulking the corners, on top of cbu, within a shower an advised practice? If so, what works the best?

For regular showers, you tape and thinset the corners of the CBU, then caulk the corners of the tile. You can caulk before grouting, if you wait for the caulk to cure. If you caulk after grouting, clean out the grout from the corner first.
